Glmer failed to converge Nov 12, 2015 · Since the likelihood differs by <0. "Solving" the issue you experience in the sense of not receiving warnings about failed convergence is rather straightforward: you do not use the default BOBYQA optimiser but instead you opt to use the Nelder-Mead optimisation routine used by default in earlier 1. Non-linear relationships between predictors and the response variable. Setting to 0 gives a less exact approximation, but the model is more likely to at least run without errors. I am using a mixed effects model using glmer(). One just needs to find the number of userId 's that are 00, 01, 10, and 11. Here is what I entered in R: data = RprodHSNS, family = "binomial") I get 2 warnings: Model failed to converge with max|grad| = 0. 00247863 (tol = 0.
