Hello Rick,

I am fairly new to SAS programming (I have passed the Base SAS Certification Exam) but am truly limited to Data step type manipulations at this point. I am having a difficult time finding references online to assist (in a very methodical way) me in programmatically creating transition matrices (for example in a Credit Risk Cohort approach framework.) Charlie Huang (http://www.sasanalysis.com/2010/12/scorecard-to-create-transition-matrices.html) has provided a wonderful example of code for the actual transition matrix generation, but I am having trouble preparing the data to be used in his code. Any chance you could blog a bit about this exercise? Thanks a million!
