Over the last several weeks, I’ve blogged about two different methods for solving the small cell suppression problem using SAS Macro code. In the first, we used a heuristic approach to find a solution that was workable but not necessarily optimal. In the second, we solved the problem to proven optimality with SAS PROC OPTMODEL. But all of this leaves a few open questions…

For example, how much better is the optimal approach than the heuristic? Is there ever a reason *not* to prefer the optimal approach? And what are some other improvements and techniques that a researcher using these macros might want to know about? I’ll spend this post reflecting on our two solutions and covering a few of these bases.
