Cutting through the BS of multilevel models

Jeff Gill looks at the plethora of terminology surrounding multilevel models:

There is a plethora of names for multilevel models. Sociologists seem to prefer “hierarchical,” many statisticians say “mixed effects,” and there is heterogeneity about usage in economics. It seems reasonable to standardize, but this is unlikely to happen. ...

Some prefer “random intercepts” for “fixed effects” and perhaps we can consider these all to be members of a larger family where indices are turned-on turned-off systematically. On the other hand maybe it’s just terminology and not worth worrying about too much. Thoughts?

Silly me thought the plethora of terminology was a deliberate obfuscation effort by methodologists to make them look like they know more stuff than they actually do. For example, smarty-pants methodologists could say in casual conversation, “I know hierarchical models and mixed effects!” And unless you knew that they were the same thing, the smarty-pants methodologist would look like s/he was two things smarter than the non-smarty-pants methodologist who didn’t know either.

I may try this myself in interviews… “I know logistic regression and logit!” “I know dummy variables and fixed effects!” I feel smarter already…

EDSBL

EDSBS links the bizarro-universe version of its site, Every Day Should Be Lemsday, written exclusively using Michael Lewis’ transcription technique for Orgeron-speak (a language related to, but not exactly, Louisiana Cajun). Never mind that “Lemsday” isn’t really a day of the week in Orgeron-speak—I believe it is a contraction of “let them stay.”

Grr

Have I mentioned lately how much I despise phone interviews?

Getting rid of the pesky Welcome screen

If you’re getting the Windows XP welcome screen on a system with just a single, password-less user, here’s the solution; apparently it is the result of something broken in .NET 1.1.

The Saints go trouncing in

Like BigJim, I’m stunned by the performance of the Saints on Sunday Night Football against the Cowboys—a team that looked like it was the best in the NFC coming into Sunday, but looked thoroughly lost tonight (along with the officiating crew). Frequent Commenter Alfie and his bride-to-be certainly picked a good game to go see in person.

Another turn in the Auburn sham course scandal

Margaret Soltan shares some commentary on a report in Sunday’s New York Times on an investigation into grading irregularities involving Auburn scholarship athletes. Key paragraphs of the NYT report:

An internal audit at Auburn University found that a grade for a scholarship athlete was changed without the knowledge of the professor, raising the athlete’s average in the final semester just over the 2.0 minimum for graduation.

The grade, which was changed to an A from an incomplete, was one of four A’s the athlete received in the spring semester of 2003. None of the courses required classroom attendance. ...

The grade was changed without the consent of the instructor listed for the course, the sociology professor Paul Starr. He said he did not teach the course to the athlete that semester and did not recall ever meeting the athlete.

“It was a phantom student in a phantom class,” Starr said in an interview in his office this week. “The schedule was a very strange one. You don’t cook up a schedule like that yourself. There was obviously some kind of guidance and special allowances with someone who had that kind of schedule.”

Starr said he found out about the grade change, which occurred May 12, 2003, only eight days ago, when he received an e-mail message as part of the internal audit. The information systems auditor who sent the message, Robert Gottesman, said the audit had nothing to do with the sociology department or the athletic department. It is not known whether the grade changes were widespread, but other sociology department professors received e-mail messages from the auditor this week.

The e-mail message Starr received Nov. 29 said, “As part of an ongoing audit, Auburn University Internal Audit is reviewing changes made to grades where the documentation was signed by someone other than the instructor of record.” ...

Starr said that he would like to find out who had authorized the grade change but that he had heard nothing since replying to Gottesman on Nov. 30.

“I want to know more about the circumstance,” Starr said. “If credit is assigned by my name, I should know the background to it, whether it was an error or an inappropriate act, because I’m the instructor of record.”

The same week Starr received the audit notice, other professors in his department, which includes sociology, anthropology, social work and criminology, received e-mail messages from an auditor.

This does not look good, to say the least. As Margaret puts it, in a nutshell: “Are we clear about what’s going on at Auburn? People affiliated with the sports program are getting in to the university computer, adding the names of players to professors’ class lists, and assigning them A’s from those professors.”

Stories of my dead-end academic career have been mildly exaggerated

As a few readers are already aware, I learned (under highly suboptimal circumstances) that SLU has offered the tenure-track equivalent to the position I currently occupy to someone else, although it is unclear at this point whether or not said someone else will be accepting said position; it is also unclear whether I might possibly receive an offer should this offer be turned down.

The good news? Three phone interviews next week, and one more I’m very confident of getting in the near future. Some of them even at places that I’d rather be than SLU… admittedly a list that has expanded somewhat since Friday.

Water, what is it good for?

A nice capper to a semi-miserable day: one of my upstairs neighbors informed me a couple of hours ago that we have no water in the building. At least the damn electricity is still on… for now, at least.

Sudden burst of popularity

After a three-month drought, I have now three phone interviews scheduled for two days next week. I have no clue what this means, but I guess it’s good.

More on media bias (yawn)

Go see my thoughts on some new research on media bias at OTB, since I’m far too lazy to cut-and-paste them here.

Debate this

My student Jim Swift inadvertently demonstrates via anecdote why I tend to avoid current events and policy discussions like the plague in my classes.

Tufte lust

Like Megan, I like much of Ed Tufte’s work—heck, I own a reprint of Data Analysis for Politics and Policy, which nobody has read in 20 years, in addition to The Visual Display of Quantitative Information and its successors Envisioning Information and Visual Explanations. But I apparently don’t like him as much as she does.

Michael Lewis Part Deux

EDSBS posts the second part of their interview with Michael Lewis, author of The Blind Side and Moneyball, spouse of Tabitha Soren, and no relation to Kurt Loder.

Death of a blogmeister

So does anyone want to take up the mantle of the table guy?

Power outages are good for my productivity

The power outage at least had one silver lining for me: it forced me to spend some time in my office with minimal distractions, which allowed me to wrap up most of the textual revisions of the strategic voting paper.

I also am continuing to fiddle with the data analysis; I’m still not happy about the 2000 results, and I’m not sure there’s anything to be done about that (beyond getting a time machine, increasing the NES sample size, and figuring out some way to get more people to fess up to voting for Nader), but the 1996 results turn out to be stronger with the IRT measure of sophistication than they were with the interviewer evaluation. Plus I got the multiple imputation stuff to work.

So hopefully during the black hole between now and student paper grading time I can get this thing polished and ready for submission to a decent journal… and have time to spare to hack together about 8 bits of my dissertation and my job talk into a SPSA paper.

In other “I actually get work done, believe it or not” business in recent days, I took care of a paper review for a journal… I wish I could say it was punctual, but in fairness the first time they sent me the paper for review it got bounced from my SLU account because I was either over my mail quota or the mail system was mid-meltdown. I also wrote two recommendation letters.

Interview follies

Apparently I have power

It would seem that the power is finally back on in my apartment after nearly four days (either that or someone has stolen all of my computer gear and hooked it up at their house... I can't really tell from work). Now I get to look forward to going home and throwing away the contents of my refrigerator.

Elsewhere: Mike Munger took notice of my plight.

OTB downtime

Those of you who visit Outside the Beltway to see my occasional posts should be advised that OTB is going through a bit of downtime at the moment due to a huge spike in search engine traffic to the OTB “Gone Hollywood” site. James Joyner currently has no ETA for when the site will be back up, but hopefully it will be soon.

Mike Munger might be my governor*

My ex-boss outlines his public education voucher proposal for North Carolina, which of course is far too sensible to become policy but nonetheless is quite appealing. Money grafs:

Now, it is true that not all charter schools are so successful, though it is also true that even the worst charter schools are no worse than the lowest-performing public schools. But think about it: what happens to a charter school that parents aren’t satisfied with? It closes, because its enrollments fall below the level required to secure sufficient funding to continue. What happens to a traditional public school that parents aren’t satisfied with? Nothing, because public schools are not just the last resort, they are the only resort for parents who are denied a choice.

Now, you can say that everybody has a choice. After all, there are private schools. And there is home-schooling. Both of these options have been selected more and more often in the past decade. Those choices are not enough, however. Private schools are not plentiful, and they are very expensive. Home-schooling is expensive too, in its own way, and not everyone is able to teach bright students the challenging material they need to know to succeed in the 21st century workplace.

Prof. Munger also responds to critics of his choice to use Amtrak to get to a conference in Charleston, a response that I suppose applies equally well to my choice to commute most days via Metrolink (even though it takes twice as long as driving and is a pain in the ass).

I will, however, add two minor quibbles: First, to the extent that our country’s involvement in the politics of the Middle East and other unstable regions of the world is driven by demand for oil, the critique that this involvement is tantamount to a subsidy to driving is only half-correct, as the other forms of transportation that are alternatives to driving either also require oil as a fuel, use a substitute fossil fuel (like coal or natural gas) whose price is dependent on the price of oil, or depend on electricity generated from fossil fuels. If Amtrak were run on electric power outside the Northeast Corridor, and the bulk of U.S. energy needs were supplied by renewable sources or nuclear power, my esteemed ex-boss’s account of implicit subsidies to passenger cars and airlines would be more convincing.

Second, highway fuel taxes account for a larger share of the funding of highway construction and maintenance than Mike’s account suggests; indeed, at the federal level the 18.4¢ per gallon tax is used almost exclusively for transportation—the bulk goes to highway construction and maintenance, although significant chunks of the money are diverted to the mass transit account and to “transportation enhancement projects” including non-motorized-vehicle projects and historical preservation. At the state level, however, Mike is correct that many states siphon money from their fuel taxes—typically of similar magnitude as the federal excise taxes on gasoline and diesel fuel—into general spending programs.

I suppose the moral of this digression is that I should start doing more transportation policy stuff in my research, since clearly I know far too much about it for it to be a healthy hobby.

* If I get a job in North Carolina (hint, hint). And Mike turns out to be the luckiest third-party candidate for a state governorship since Jesse Ventura.

Accentuating the Neutral

Here’s a big shocker, I know:

What American accent do you have?
Your Result: The Midland
 

“You have a Midland accent” is just another way of saying “you don’t have an accent.” You probably are from the Midland (Pennsylvania, southern Ohio, southern Indiana, southern Illinois, and Missouri) but then for all we know you could be from Florida or Charleston or one of those big southern cities like Atlanta or Dallas. You have a good voice for TV and radio.

A minor disclaimer: I tend to use a weird mix of formal speech and Southern colloquialisms in everyday conversation, so I do have my Southern “moments” when speaking, but if I avoid Southern terms (primarily “y’all”) I pretty much sound like Tom Brokaw.

Tubby Studies

One of the dozens of “last forms of acceptable discrimination” will get its place in the academy if “fat studies” is added to the curriculum. Somehow I don’t see the study of William Howard Taft (or, for that matter, William Jefferson Clinton) fitting very well into this research program.

Double-entendres of the night

Brent Musberger just said on national television—and I quote literally—“the road to Glendale is paved with Trojans.”

I wish I were making that up. What’s worse is now I can’t get that image out of my head.

Brent also just said that a Notre Dame player was penalized for “pulling out early.”

QoTD, Egg Bowl edition

From Michael Lewis’ The Blind Side, explaining the passions surrounding the Egg Bowl to outsiders:

The game served as a proxy for the hoary Mississippi class struggle, between the white folks who wore shirts with collars on them and the white folks who did not. Mississippi State was a land grant college, originally called Mississippi A&M. The desperate contempt Ole Miss football fans felt for Mississippi State was echoed in the feelings of fans of the University of Texas for Texas A&M and fans of the University of Oklahoma for Oklahoma State—formerly known as Oklahoma A&M. These schools were not rivals; they were subordinates. Theirs was not a football team to be beaten but an insurrection to be put down. This notion was most vivid in the Ole Miss imagination: that the state of Mississippi, with the sole exception of the town of Oxford, was once a Great Lake of Rednecks. In recent decades the earth had warmed, and the shores of Great Lake Redneck had receded, so that, strictly speaking, perhaps it should not be described as a lake. But still, the residue was a very large puddle. And the one place in the puddle deep enough to ruin a shiny new pair of tassel loafers was Starkville, Mississippi.

EDSBS interviews Michael Lewis

Orson Swindle at EDSBS has posted part one of a two-part interview with Moneyball author Michael Lewis, wherein he discusses his new book The Blind Side: Evolution of a Game and the primary subject of that book, Ole Miss offensive tackle Michael Oher.

The following passage of the interview warmed the cockles of my heart—by way of explanation for the warming, the Ole Miss political science department used to house the criminal justice program until it was spun off along with the rest of the programs that a four-year university (much less the College of Liberal Arts) had no business operating into a separate school:

[ML:] On behalf of [Oher’s] mind, I would say…I’e watched him over the past few years, and he’s become a much more verbal person. He is intelligent–he’s not stupid. He’s shrewd, and he’s sensitive. The way he’s impressed me is not with his grades in the classroom, though I’m sure he’s worked to get them and they’re not entirely fraudulent.

OS: We’re not talking about Auburn, here.

ML: Well, I do think we’re talking about that. All these schools have the smooth track for the football players–

OS: Sociology at Auburn, Criminal Justice…

ML: It’s funny. You watch the Saturday football games, and if it’s West Virginia playing, all the football players are “sports management” majors, but if it’s Ole Miss playing, all the football players are “criminal justice” majors. So you get the sense that every school has its major for the football team, and it’s different from school to school. All the Ole Miss football players aren’t majoring in criminal justice because they have a deep and sincere interest in criminal justice. It’s that that’s where you go to get the grades.

And Michael is majoring in criminal justice. That’s not a great sign, but he’s doing well. And this is what is true about him: he’s not just “not dumb,” he’s intelligent and sensitive. When he sits down to write something, it’s actually impressive. He’s got things to say. The mind he’s got is a good and interesting mind. That that is true despite his first sixteen years on the planet is amazing.

Incidentally my copy of Blindside was allegedly going to be shipped to my mom’s house in Memphis by Amazon.com today for delivery Wednesday, according to the checkout screens, but given the current delivery estimate of next Monday I doubt that actually happened. Regardless I promise a review soon.

Update: Never mind; I just got an email from Amazon.com that has a tracking number saying it will be delivered tomorrow. So, depending on how engaging a read it is, I may have a review up by the end of this weekend.
