Hear, hear ! S-plus could have been a Microsoft product. It's bloated and slow and it's everywhere. Of course C does not stand for "computer". The naming chain is CPL => BCPL => B => C. See Steve Summit, C Programming FAQ's, number 20.38. At 12:59 AM + 2/23/00, Radford Neal wrote: >In articl

Gus, You are making a defense of studying distributions as they are thrown at us by nature/circumstances, This seem the way to go to social scientists because we tend to believe that our causes are embedded in all sorts of complex interactions and can not be isolated from their context, If we l

Jerry, You are correct that the same data set can support a number of SEM models. This is not the case with corresponding correlations/regressions, however, CR discloses THE causal model for a given set of data, To debate whether or not this disclosure is provable or not when we model phenomena

Those are excellent questions Thomas. Many programs expect students to learn statistical computing "by accident". Statistical computing is too important for applied statistics to let that happen. S-Plus is an excellent statistical computing tool. You can look at a syllabus for a statistical co
