Re: [R] random slope models with lme --> failured to converge

Hi, I have been working with LMMs for a while now and convergence has proved to be a very common problem. Right now, your model has two random effect terms, that is, one for the intercept and one for the coefficient of the "treat" variable. This implies that the default variance-covariance mat

Dear all, I am working on a data set in which I have sequentially measured egg temperatures ("eggtemp") in birds incubating in different ambient temperatures ("treat", sample data set below), "id" is not replicated within treatment. id treat eggtemp 1 79 3 30.90166 2 42 3 34.9
