Completion warning in glht [closed]

Question

I am running a sequence of post-hoc tests with glht (mutcomp package), but the function summary warns me that the algorithm ends with an error > abseps as in:

> hr.ph <- glht(hr.lm, linfct = ph_conditional);
> summary(hr.ph)

Warning messages:
In RET$pfunction("adjusted", ...) : Completion with error > abseps

Does anybody know what that means? I think it is a matter of modifying the parameters of the algorithm that summary runs. Looking at the documentation, I could not find a way of actually doing so. Do you have any suggestion? Also, how does one know the default values of these algorithms?

Answer 1

This is a warning thrown from mvtnorm::pmvnorm. It can in some cases be avoided by adjusting maxpts from the default 25000, such as:

summary(hr.ph, test = adjusted(maxpts = 10*25000))
