jamovi

Hi! What is the matrix that jamovi uses when performing EFAs? Is it Pearson? I have ordinal variables and should use the polychoric matrix. Is there anyway to set that? Thanks!

Hi! The EFA uses a pearson correlation matrix indeed, and there's no way to use a polychoric correlation matrix at the moment. We use the psych R package to compute the EFA results, and I'm not sure it's possible to use a polychoric correlation in the function provided in that package.
