Today, taking a break from writing the grant proposal that has no end, I found myself thinking about easy ways to explain and understand standard error. To understand standard error, you have to have some statistic that you’re discussing the standard error of. As a random example, let’s just take the mean. T-TEST PROCEDURE FOR…
The census now allows more than one race to be checked. For many years, friends of mine in inter-racial couples when they registered their children for school would check the “Other” box for race, rather than pick black or white. Although an individual’s census form responses are confidential, you certainly are free to tell anyone…
<- On the lake shore last night It wasn’t until a banker sneeringly said to me, “So, you’re a lifestyle business.” That I realized lifestyle business was not, as I had mistakenly thought, people who called themselves “life coaches” , Mary Kay consultants, personal trainers, financial consultants or other businesses that are telling you what…
I’ve forgotten more about statistical software than you’ll ever know! I don’t know why people ever say this in a bragging tone because I consider that to be my problem. I’ve forgotten it. Today, I needed to do a confirmatory factor analysis with someone using AMOS. They wanted it in AMOS so that is what…
I was going to come back to the hotel after work and finish up my paper for the Western Users of SAS Software (WUSS) conference. This one is called Better-looking SAS for a Better Community. It was going to use the analyses I did of inequality in America and presented to urban Los Angeles middle…

All three papers are in the SAS Essentials strand, which is designed to provide a jump start in their career for relatively new programmers. I’ve given some version of this talk a few times before, and I sometimes think it…
We’re one of those small businesses that congress claims to care so much about. We’re also, many years, a couple that makes over whatever the limit is for raising taxes. Whenever we see a tax credit, whether it’s for child care, or alternative minimum tax or whatever, we just ignore it because we know we…
I have learned not to be too smart for my own good. Yesterday was an example. My client provides many different types of services to the consumers who use their program. There are about 15 different options, from counseling to on-the-job training to assistive technology. We want to get the total number of services each…
Been working with SAS a lot lately to get the data in shape for a new client. Here’s one of the problems I ran across. We want to get the average pay rate for people who got jobs as a result of our client’s services. However, when one of the people they served did not…
When people ask me what type of statistical software to use, I run through the advantages and disadvantages, but always conclude, “Of course, whatever you choose is going to give you the same results. It’s not as if you’re going to get a F-value of 67.24 with SAS and one of 2.08 with Stata. Your…
