Dear `lme4` authors, thank you for this interesting implementation in pure R.
I am trying to "sandbox around" with the estimating function for the multi-level linear model. The first thing I noticed…

Hey,
I think this issue is to do with my lack of understanding / user error rather than a bug - but any advice would be really appreciated it.
My piecewise SEM model initially was a poor fit - d…
