Hi all, I am a facing a convergence problem when I test for variability of a slope among groups in lme. a) How do I know how many iterations the program is running? b) How do I increase the # of iterations c) Do I include the command to increase iterations in my equation?
There seems to be consensus among authors of iterative routines in R to issue control parameters to functions in lists with names like "control". Looking at the help page for 'lme' suggests its authors have followed that pattern. This is a question that would get a wider audience of knowledgeable minds regarding lme and cousins if it were directed to the sig-ME mailing list.
