I recently had a student in a SAS Enterprise Guide class declare that EG was the next best thing since sliced bread. I couldn’t have agreed with her more! In this post, I‘ll share four ways where EG outperforms SAS code –yes I know you’re a cod…
Efficient acceptance-rejection simulation
A few days ago on the SAS/IML Support Community, there was an interesting discussion about how to simulate data from a truncated Poisson distribution. The SAS/IML user wanted to generate values from a Poisson distribution, but discard any zeros that are generated. This kind of simulation is known as an […]

Inverse hyperbolic functions in SAS
I was recently asked, “Does SAS support computing inverse hyperbolic trigonometric functions?” I was pretty sure that I had used the inverse hyperbolic trig functions in SAS, so I was surprised when I read the next sentence: “I ask because I saw a Usage Note that says these functions are […]
NOTE: More on Ishikawa
I recently mentioned the use of Ishikawa diagrams for assistance with problem solving. I have frequently found them to be of value. However, what I had never realised, until my friend Chris Brooks pointed it out, is that there’s a PROC ISHI…
