Upfront confession – I completely copied the first part of this from a macro Paul Dickman wrote in 1999 because it did ALMOST exactly what I wanted. I tested it several times with different data and on different computers to see that it worked the way I expected. I actually found it on some random…
Although I tell my students all of the time that statistics is everywhere, even I did not really see where mixed martial arts, free rice and PROC SURVEYSELECT could possibly have anything in common. Here is what happened …. Mixed martial arts Darling daughter #3 after the Olympics decides not to go to college as…
My initial exposure to Occam’s razor came in my first undergraduate economics class. Perhaps due to my tender years, it made a great impression, and I have tried to apply it ever since. In short, Occam’s razor advises us when presented with competing, plausible choices, the…
1. Use the data sets in the sashelp directory for dummy data. 2. The RANUNI function is worth remembering Today I needed to check something.

In a few (okay, a lot) of my previous posts I talked about how you could get set up with SAS On-Demand, problems you might have, programs to run. Now we get to the crux of the matter. Why? Let’s assume that you are like most professors in America and your students are like most…
Last week, I was relaxing in bed reading a book when my daughter, Julia, came storming into the room. She demanded, “Mom! Have you heard of SOPA?” I informed her that yes, in fact, I had. She said she had read about it on Google and written a letter to her Congressman. Students in her…
The other night, I was annoyed. This is a common state for me, so not too surprising. I was annoyed because I could not log on to SAS On-demand. I would click the icon on my desktop and the log in screen would come up with my username filled in. About a minute after I…
Three times within a very short period I have seen technology offerings that I thought were an epic fail. In one case I was a beta tester, in one, a regular user and in the third a personal friend of the founder. All of them, I thought, had brilliant ideas that fit a real need…
