The current version of lme4 uses C code for the inverse link function so you would need to modify the function lme4_muEta in the file lme4/src/lmer.c If you look at the other inverse link functions defined in that C function you will see that it is not a matter of simply writing down the inverse link. You need to be very careful of the edge conditions and most of the code is devoted to those kinds of checks. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
