Since I had done a few youtube videos on using SAS Studio, I thought I would add them to my blog. This one uses the characterize data task to take a quick look at the data, but I suppose you could have guessed that from the title.

SAS macros (well, any macros, really – Excel, whatever), can be a great thing. While at first glance they may look a bit hairy, if you have repetitive tasks it makes it easier to debug your code. That may sound nuts at first glance. How can adding something with the %global %do &var and call…
Listen my dears and you will learn the difference between incidence and prevalence and why effective treatment for a disease may mean that more people have it. Prevalence is the number of people in the population who have a disease. It is computed as Number of people with disease X 1,000 Number in population…

My niece, Samantha, should be far more trusting at her tender age. She was skeptical – skeptical, I say! – that I once worked at a job where I got so bored that I started coding my SAS statements backwards, typing a semi-colon first and then working backwards, say to PROC . Non-naive nieces aside, it…
