GLMM revisted

March 5, 2010

(This article was first published on Shige's Research Blog, and kindly contributed to R-bloggers)

A short while ago, I reported some discrepancies between the results produced by “lme4″ and other R packages as well as Stata. Today I upgraded to the most recent version of “lme4a” and re-ran my model. The error of false convergence disappeared and the new results are very much in line with other packages.

I am glad that the problem eventually got sorted out.

For this version, the adaptive GH quadrature has not been implemented yet; so the only option to estimate a GLMM is laplace transformation.
