I watched Black in America: Silicon Valley, The New Promised Land with Soledad O’Brien on the accelerator for black entrepreneurs. It was a terrific show and I highly recommend it. An interesting comment was made by one of the venture capitalists when O’Brien asked him why a white, wealthy male like him cares about diversity…
Continuing on with questions students asked at the end of the semester … Note that the following questions were asking what I personally do, and I answered the same way. These are not rules that anyone has to follow, like taking the square root of the variance to find the standard deviation, but they are,…
It’s that time of year, near the end of the semester, when I ask students to write down any questions they may have about material covered in the course. This semester I am teaching Advanced Quantitative Data Analysis. I thought other people might be interested in the answers to the questions students asked as well….
Anyone who has ever taught has probably had this experience … you are reading a student paper and think, “I really don’t understand what he/ she is trying to say here.” Like most professors, you probably assume that in these situations, the students aren’t very clear on the concepts themselves. You’re probably…
Today was a lesson in why one should always be a little leery of mean substitution. I had downloaded a data set to use as a logistic regression example for my class tomorrow. It happened to be the 2010 Monitoring the Future study and I was particularly interested in school drop out. This is a…
Let the buyer beware – that phrase certainly applies to open data, as does the less historical but equally true statement that students always want to work with real data until they get some. Lately, I have had students working with two different data sets that have led me to the inevitable conclusion that self-report…
It’s about time I got some recognition ! You can claim your own Love Stats award here. Careful, of undeserved awards, though. The last person who falsely claimed a Love Stats award had multicollinearity in his measures, a high VIF and died of complications of homoscedasticity. You have been warned.
I am tired of hearing that men in technical fields cannot meet women. Some stupid company even went so far as to say that they had hired hot women to work at their company so now they were going to have no problem attracting good programmers and engineers. This is stupid on so many levels….
Giving a whole new meaning to “computing in the cloud”, I finished up my paper “A gentle introduction to survival analysis” for the Nevada SAS Users Group from 30,000 feet up using on-board wi-fi and SAS On-demand. I was shocked to find that the performance was much better in-flight. Presumably, if you charge people $12.95…
I might as well give you my opinion of these two kinds of sin as long as, in a way, against each other we are pitting them, And that is, don’t bother your head about the sins of commission because however sinful, they must at least be fun or else you wouldn’t be committing them….
