Mixed model for repeated design
Posted: Fri Feb 01, 2019 8:03 am
I tried to replicate an analysis done in R (with lmer) on a design with a within factor (time, 3 measures, ordered factor) and a between factor (group, 3 groups) in Jamov (mixed model).
All the results are the same, except for the contrasts of the variable time (contrast polynomial): the linear constrast is significant in R but not the quadratic contrast
the quadratic contrast is significant in Jamovi, but not the linear constrat
How is it possible? Any suggestions will be welcomed.
