Their business model though is that of base SPSS for a base price, plus anything extra at an extra price, and I am pretty sure that the CART module would have to be purchased separately. -- Stas Kolenikov, PhD, PStat (ASA, SSC) -- Senior Survey Statistician, Abt SRBI -- Opinions stated in this email are mine only, and do not reflect the position of my employer -- http://stas.kolenikov.name On Tue, Oct 15, 2013 at 11:44 AM, Nick Cox <njcoxstata@gmail.com> wrote: > Thanks, Stas.
