Dear all,
I am currently trying to run a couple of robust models in Splus Version
5.0 Release 2 for Sun SPARC, SunOS 5.5 with the function lmRobMM () with
the final aim of comparing these models with the function anova(,test="RF").
One of the smaller models that I am trying to run has about 450 cases and
uses one factor as the explanatory variable (with almost 40 levels; the
larger models have one to six additional continuous variables). The
calculation of this model is running now for almost 20 hours of CPU time.
Does anybody else have experience with the efficiency of this function,
any idea whether this is normal behaviour and I just need to be patient or
on how to speed things up?
Thanks for all hints. I will summarise the responses to the list.
Regards,
