I have colleagues who hate Excel with a passion. Why, they demand to know, would ANYONE use Excel for statistics when there are so many options that are so much better? Actually, I don’t find the Excel add-on for statistics that terrible, but that isn’t even the topic of this post. I use Excel because…
Go to your local users group. If you don’t know if you have a local users group in your area, check the sascommunity.org page that lists bunches of them. There are six in California listed on their site and I heard of two others that started very recently that aren’t listed. LABSUG is the Los…
If you have a mad desire to do logistic regression with SAS On-Demand with SAS Enterprise Guide, here is a movie that shows how to do it. It is a .avi file so you may want to just download it and run it on your PC. Here is why the movie is not all that…
Here we have analysis of open data using free software with – uh, SAS? Click the links below and watch the videos. Seriously. They are too large to embed in the post. Sorry. Yes, you might think of SAS as the choice of multinational corporations with unlimited software budgets. You now have two options, if…
I may expand this into a series on software products in general. Years ago, I wrote a post on the similarities between the Rocket Scientist and SAS Enterprise Guide. Neither made a great first impression, both revealed their brilliance over time, and I am still with both lo these many years later. Experiencing both SAS…
I read an interesting question years ago, on the JMP blog, “What are 5-9 software packages you can’t live without?” That reminded me that when I started this blog almost four years ago, I wrote a post with the title “Nine software packages I can’t live without” . I never finished publishing the list, I started another list…
I decided about a year ago that it was time to write an educational game to teach math. None of the languages I knew were an optimal choice for this. I’d been programming in SAS for 30 years and it’s an excellent choice for processing the data that come in from pre-tests, student answers and…
Not a day goes by that I don’t read an article saying I don’t exist. Apparently, there are no women actually running start-ups, no Latinos in technology. No one outside of Silicon Valley is doing anything. Maybe I’m a unicorn. Or perhaps I’m invisible. If I were to actually exist, and if it was possible…
Today, I wanted to find the confidence interval for the difference between two proportions. I have SAS, SPSS, Stata, JMP, Excel and God knows what else laying around. I did not want to go to the effort of plugging the numbers into a calculator, but it really is a pretty straightforward formula, so you would…
Yesterday and the day before, I gave an example of using SAS to sort student responses into the class they were in using the DATEPART function, TIMEPART function and a few DO-loops. After making sure my code runs, I decided it was pretty redundant and thus a classic case for a macro. What I want…
