Thanks Ben, I am tryin on simulated data, say 300 repondents, 8 choice per person, only 2 random parameters... so i think it should be well behaved... so I am probably doing a mistake! :-)
Thank for poiting out the MCMCglmm package, ultimately I need to write my own non-linear untility function, so I do not think I can use standard packages hence I am writing my own code... you know if MCMCglmm can deal with non-linear in parameters utilities, Cheers, Caro -- View this message in context: http://r.789695.n4.nabble.com/bayesian-mixed-logit-tp4304327p4306498.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
