Working with ever-changing CDISC standards

When Jack Shostak and I first started thinking about writing a SAS book on implementing CDISC (Clinical Data Interchange Standards Consortium) standards, we held one truth to be self-evident: that at least some parts of the book would be outdated before it was even published.

Now I just start to build my SAS library one by one. I will most probably not buy more SAS books as […]
