GLMM using cplm package in R
Hi all, I've been trying to build a glmm using cplm with a tweedie distribution. I tried to follow the cran specifications but can not get the following code to run (all prereq packages have been successfully installed): TweedieGLMM.M1 = cpglmm(COOPPERMIN ~ fSEX + fAGE + (1 | fISIS), data = SDdata, link = 2) The error I receive is: Error: no valid set of coefficients has been found, please supply starting values. Do I need to specify an additional value in the "link" argument? Or does this have something to do with specifying the initial values for the different chains? Any insight would be appreciated. -Gavin
