I saw the macro referenced in a couple of SAS User Group papers. One place it is located is here: Macro Programs | Applied Missing Data .com I also saw Yuming Ning listed as the author at another location. Though, I believe when using it, you can only use all numeric or categorical data (or perhaps numeric and categorical coded as integers). I would be interested in seeing the results from the macro compared to the results from a program where the test is built in. How do you get at the MCAR test in Proc MI?? Side note, I have your Simulation book Rick and just upgraded to SAS 9.4. If I get a chance I would like to try running the code to simulate multiple categorical variables. I could not get it to run right before. There was an erratum in the book and my version of SAS was before the 9.3 second maintenance version. It does take much to confuse me!
