Does it mean, that the problem of computing the "right" nr. of degrees of freedom for the t-values of a linear model does not exits (or is less of a problem) for non-linear models? Are the significances that glmer produces (at least in case of logistic regression) based on the Wald statistic or may be on an LRT test? Thanks for any explanation!
