This happens in two situations: •The model simply doesn't fit the data very well. Perhaps you picked the wrong model, or applied the wrong constraints. •The initial values generated a curve that didn't come close to the points.

Webb6 feb. 2024 · The version of lmer in lmertest apparently has a more conservative check for convergence than the current lme4 version. The problem in lmertest::lmer is caused by the variables being on vastly different scales, which can make some of the optimisation routines unstable, and thus generate the warning. If you re-scale, the problem vanishes: Webb9 okt. 2024 · It’s not surprizing that convergence difficulties are being encountered.
