One of my favorite movie lines ever comes from The Princess Bride, “You keep using that word. I do not think it means what you think it means.” Sometimes I want to say that to people who want me to give an explanation for every result that is “significant”. Perhaps you would like to test…
Since the whole presentation Patricia Berglund gave on survival analysis is available at the SAS Global Forum takeout section (which I explained yesterday, you should have been paying attention), I just wanted to add a few highlights here. 1. Using PROC LIFETEST with a STRATA statements is a very dandy way to show survival curves…
The first cool thing you should know about Dr. Patricia Berglund is that she and several others put their slides and more up at the SAS Global Forum take-out section. That is NOT, contrary to what you might believe, a place where you can pick up some really good Chinese food to eat while listening…
From time to time I get asked, “Can you recommend a book like Structural Equation Modeling for Dummies?” My unspoken thought is always, “You’re f***ing kidding me, right?” SEM isn’t the sort of thing done by dummies. Well, ask no more if you want straightforward, basic treatment of CALIS – the SAS procedure for structural…
Despite the title, this is not the new show in Las Vegas. John Sall is Mr. JMP . In fact, it is said behind his back that JMP actually stands for John’s Macintosh Project, this being the product SAS started about the time that they made the move away from running SAS on Mac OS…
In three minutes before the next statistics session, here’s some more on the opening session last night.

In the shower this morning, I was thinking about how seldom true longitudinal designs meet the assumption of sphericity. This is the point where one of my daughters always makes a comment about what other people think about in the shower. I don’t want to hear it. Sphericity is an assumption that all correlations among…
If you are the right age to have watched re-runs of the show on Nickelodeon, Clarissa Explains It All, then you are the age group today’s blog was written for. And don’t tell me the previous statement is grammatically incorrect. After having looked at these results, I’m already pissed off (note to self: don’t swear…
Hispanic, female, Ph.D. statistician who loves math. Hoo-wee, we hit the lottery! Let’s have her come talk to our inner city school children about STEM education. It’ll be SO uplifting. Ri-i-ight. (Oh, by the way, one million brownie points to the teacher who knew me but invited me anyway.) Given that the students are 12…
I was very thrilled to be invited to speak to six classes of seventh- and eighth-grade students at an urban school. Actually, they wanted me to speak to seven classes but there is no way on earth I am getting up at 6:30 a.m. or whatever ungodly hour would be required for me to make…
