Prediction with confidence intervals not yet implemented for weighted regression

[jariji]

I just hit this error.

GLM.jl/src/lm.jl

Line 267 in f149f2b

length(mm.rr.wts) == 0 || error("prediction with confidence intervals not yet implemented for weighted regression")

One Discourse answer suggests using glm(f,d,Normal()) instead of lm as a workaround. I'm not sure if that's equivalent.

These will give the same predicted values, but I'm not sure they would give the same confidence intervals (T distribution vs normal distribution). Anyway the result will be statistically sound in both cases at least.
