NaN correlation in documentation #819
Description
The documentation reads:
(Notice that the variance component for days: 1 is estimated as zero, so the correlations for this component are undefined and expressed as NaN, not a number.)
https://juliastats.org/MixedModels.jl/dev/constructors/
I might be misinterpreting, but I don't see any NaN correlations or 0 estimates.

Ah, we updated the printing of some edge cases around those zeros and so the relevant entries are caught as systematically undefined/set and are replaced with
.You'll still get NaNs when a variance is "naturally" 0, but that example no longer show it.Thanks for the catch.
constructors.mdto say NaN correlation is printed as a dot, fixes #819 #822
