Two or three lifetimes ago, I was an Associate Professor at a small, liberal arts college, teaching, among other things, lifespan developmental psychology because, well, somebody needed to teach it and I had published several articles on assessment of families and other semi-related issues. One debate in the field, I learned, was how much of…
A few days ago, I tried installing Enterprise Miner for, I think, the third time. The first time, I could not get it to work, saw we needed something called a planned install for which I needed a plan file which I was to get from my SAS administrator, who happens to be me and…
The other day I needed to have a job run daily. My two efforts at solving this problem failed. These were: 1. Ask the six people hanging around for no particular reason how to do it. All vaguely remembered learning that at some point and had forgotten specifically how to do it. 2. Using Google…
I have long suspected that the main role of other people on this earth is to annoy me. Take FIPS codes. FIPS stands for “Federal Information Processing Standard”. Does no one know the meaning of the word “standard” ? A FIPS code is a useful thing. For counties it is a FIVE digit code. Got…
Normally, things are very quiet in the De Mars household. Being out-numbered by daughters, two to one, my husband and I feel as if we need to maintain a united front against the younger generation.

Grown-ups lie to kids. I have discovered this. When I was young, my mom did not have a lot of money, and so things like trips to Disneyland, when they occurred at all, were on an extremely tight budget. No buying candy, souvenirs or extras. I swore that when I grew up, went to graduate…
In trying to decide what courses to teach, it is not as simple as looking at what products are used the most because, to some extent, we are looking at the result of a self-fulfilling prophecy. No one calls up and tries to order a product or schedule a class for something that they don’t…
I knew it! I am finally getting some time to finish reading The Black Swan and I came across this statement, “Makridakis and Hibon reached the sad conclusion that ‘statistically sophisticated or complex methods do not necessarily provide more accurate forecasts than simpler ones’. ” I have thought this for years. Like most of my…
A few days ago I gave an example of multiple imputation but I glossed over a number of things, which is fine when you are just getting into a topic, or when the mad scientist part of your personality has taken over, but seriously now … Our story continues … when last seen, our data…
