No matter how experienced you are, you will still make the most obvious errors, and sometimes, (if you are me), the more obvious it is the harder it is to spot. I mentioned wasting time trying to figure why my quintiles weren’t exactly 20% each when the answer was pretty obvious. I am getting better,…
I’m taking off for two weeks on a working vacation defined as I will be working while the rest of the family is on vacation. I found it interesting that the list of what I NEEDED to do in getting ready was Go to the Apple store and pick up a 500 GB hard drive….
We are looking for data to use as an example of propensity score matching for a couple of upcoming workshop / classes. Since the data I have used previously belonged to other people, I needed to come up with an example that could be stated in a format something like: Controlling for X, Y and…
Oddly, Sandra Scarr, author of both the seminal study on IQs of black children adopted into white homes and the book on child care, “Mother care/other care” gave this advice to working mothers. I quoted her years ago in a chapter I wrote for a book used in Freshman 101 courses. The title (of the…
Years ago, I happened to be at a meeting where two well-known African-American researchers were speaking. Like many conferences, there were “round table” luncheons with the famous people that you could attend.

I learned at St. Mary’s Catholic School that envy was a sin. Good thing I am going to mass on Thursday, because I am suffering from a good deal of envy lately. First there is blog envy. If you have not checked out The Berkeley Blog, I highly recommend it, starting with this post on…
I thought it would be really interesting today to get back to looking at SAS Enterprise Miner, especially the text mining. I thought it would be cool to take another look at Statistica. I also thought it would be cool to finish a blog post I started on power analysis for mixed models. And I…
Since I was a female engineer over thirty years ago, I’ve seen quite a bit of change for women in technology. Still, both then and now, a common complaint is about how women are held back by lack of mentors. Now, being on the other side of the desk, I can see one possible reason…
It occurred to me today that I could not remember ever meeting another Hispanic statistician and I got to wondering how many Hispanic statisticians there actually are. I started with Google, source of all knowledge. I found a blog post from two years ago that said there were 12 Hispanics out of 15,904 members of…
