Web8 sep. 2024 · I think that clears it up -- your fixed effects are perfectly collinear (that is why the smallest singular value is 10^-14). Your design matrix has 6 columns (that is why you are getting 6 singular values, or you can just check md.exog.shape).This may not have been what you intended with your formula, which has only four terms on the right side.

WebOne simple solution is to check the scaling of your predictor variables. If they’re on vastly different scales, the model might have trouble calculating variances. So if they differ by an order of magnitude (or more), you may need to simply change the scaling of a predictor. http://r-spatial.github.io/gstat/reference/fit.lmc.html
