Three-way interaction in MLwin 2.32 vs lme4 in R
Posted: Sun Jun 02, 2019 8:44 pm
Hello everyone,
I compared the results of MLwiN and lme4 on a set of data from our lab by computing the exact same models in the two programs.
Both programs gave the exact same results for the two-way interaction models. However, after adding a three-way interaction, the results significantly started to differ betwenn MLwiN and lme4. Notably, the two-way interaction became significant in MLwiN but not in lme4 (see the linked picture for details).

Would you know what is the cause of this difference?
Best regards,
David
