How long have you been using SAS®?

32 years.

What SAS products have you used in the past? What products and solutions are you currently using?

Base SAS and SAS/STAT®.

What is a problem you have solved using SAS?

I first came across SAS in 1980 when I was completing my master's degree. My research required a nested analysis of variance be carried out, and there was no current solution capable of doing that - except for this new software package called SAS, which had a procedure for doing all kinds of general linear analysis. It saved me from having to code the nested analysis of variance in FORTRAN, which would have taken me months to complete.

What is the most innovative way you have used SAS?

I combined Base SAS and macros, PROC LOGISTIC and Monte Carlo methods in a simulation study of the Hosmer-Lemeshow test using sample sizes currently found in health care databases. My analyses showed that even with sample sizes as low as 10,000, the Hosmer-Lemeshow starts to flag as significant trivial departures from goodness of fit (published in Critical Care Medicine, September 2007).

What is your most memorable SAS moment?

When I started my postdoctoral fellowship in 1983, my new department was using different software. I explained to the database administrator that there was a better way of handling data and introduced him to SAS. Within six months, the DBA became a SAS devotee. My reputation within the department rose substantially.

How has SAS changed in the time you have been using it?

The two most dramatic changes have been going from a single manual to tens of thousands of pages of documentation, and the evolution of SAS/STAT from a PROC MEANS/univariate/GLM tool to a full-fledged statistical package.

Have you ever attended a SAS users group meeting or SAS Global Forum? If yes, please list them.

I've attended about six SAS users group meetings (mostly SESUG) and one SAS Global Forum.

Has your work with SAS been influenced by any other members of the SAS community?

Absolutely. SAS was ahead of the curve in terms of data warehousing, and I learned a lot from the developers of SAS/Warehouse Administrator®. I received support numerous times from SAS when I came across a problem that was particularly difficult. Finally, the SAS-L group is an amazing resource.

If you could point a new SAS user to one resource, what would it be?

SAS online support; I've used many analytical tools during the last three decades, and SAS offers the best support, hands down.
