JASP: LMM: Test model terms, where?

hugoquene

Dear all,

While tinkering with frequentist Linear Mixed Models in JASP 0.17.1 I read this note in the fit statistics table (italics added).

Note. The model was fitted using restricted maximum likelihood. Please note that models with different fixed effects cannot be compared when REML is used. To use ML, switch 'Test model terms' to 'Likelihood ratio tests'.

I understand this note, but I could not find how to specify `method=ML` or `REML=FALSE` (as I have done in lme4::lmer) in the JASP options nor in the Help info. Nor did I find the "Test model terms" field to switch something. What am I missing? With kind regards, Hugo Quené

Under "Options", test method (on the left) is set to Satterthwaite by default, you can change it to Likelihood ratio tests, like so:

The output now shows ML estimation:

Thank you patc3, this helped me a lot! Best, Hugo
