Any time you add another layer of complexity you better have a damn good reason. I’m often skeptical of proponents of both Item Response Theory and multiple imputation procedures, not because either IRT or MI is a bad thing in itself but because its inclusion makes data analysis and reporting more complicated. At the National…
I was very happy to get an acceptance letter from WUSS telling me that my class proposal for the 2011 conference was accepted. I’m usually happy to get acceptance letters in general but this was particularly nice since I have gotten the first four chapters of my naked mole rat book done and the next…
I admit that I am hardly a typical user for statistical software, given that I had to go online to download a file with less than 7,000 records and less than 500 variables. STILL, I have to say that PSPP was a disappointment in a great many ways. This is NOT to say that it…
When last seen, our heroes were attempting to write a book with the title Beyond SAS Basics: Tips, Statistics and a Naked Mole Rat The first chapter was entitled After the Data Step. The first half of it was posted here earlier which you would know if you were following this blog in the probably…
How to make SPSS 18 do graphics whether it wants to or not … SPSS isn’t the statistical package I use most often – a few times a month when clients request it. I have SPSS 18 on a Mac and it works fine pretty much, until recently when someone felt the need for a…

I wanted to learn how to use smashwords, for reasons completely unrelated to this blog, SAS or statistics, but I thought it would go much faster if I had an actual project to work on. I considered writing a serious book for researchers on SAS Enterprise Guide, but then I decided that I did not…
I was very busy this weekend working on the semi-annual site update (I am SO getting last place in the Search Engine Optimization contest) and starting on my book – Beyond SAS Basics: Tips, Statistics and a Naked Mole Rat and on TOP of all of that, I had to take the world’s most spoiled…
Now, I’m not as extreme as the person who created a SAS Tetris game, (Richard DeVenezia, in case you were wondering) but I still try to do just about everything in SAS, if only to prove that I can do it. Why would someone who has been using SAS for 28 years decide to pick…
I’m doing a workshop at the San Diego SAS users group meeting on Wednesday and had suggested opening the session with a clip of my daughter’s last amateur fight. Someone politely commented, “Uh, I guess that would be okay, if it was, uh, relevant.” Fair question, how can martial arts be related to statistics or…
