Test Driven Analysis

I mused over Test Driven Analysis on this blog before, but it was Richard Pugh’s talk on SAS to R Migration at LondonR last week that brought the topic back into my mind and clarified a few things. Rich’s presentation focused on the challenge of how to ensure that the new system ® would provide the same answers as the legacy system (SAS). This is when it clicked with me: My brain is just another system as well.
