RE: SAS program or SAS macro to prepare NonMem ready data

From: "Leonid Gibiansky" leonidg@metrumrg.com Subject: RE: [NMusers] SAS program or SAS macro to prepare NonMem ready data Date: Sat, December 11, 2004 12:23 am Do not get me wrong: I am not arguing against SAS or for S+: I think, this is a matter of preference and depends on the problems that you need to solve. I was commenting on a particular question: data set creation for PK/PD modeling. In this setting, S+ memory problems/limitations do not manifest itself. Even if they would, this is not related to the performance of the sort function but rather to memory management. For data set creation, data diagnostics and NONMEM model output diagnostics S+ (or R) should be adequate. If you try to analyze results of 1000 simulations of the trail with 1000 patients you better use SAS: most likely, S+ will not be able to handle it. To me, the major limitation of SAS is cost while S+ is not expensive and R is free. Leonid _______________________________________________________
