How can I check the parallel line analysis assumption in Ordinal logistic regression?

This is not possible yet afaik, however it would be very desireable to have this option in JAMOVI.
At least, the documentation/ebook should contain a hint that this assumption needs to be tested before coefficients from the model can be considered valid.
Assuming JAMOVI draws on polr for ordinal regression, this assumption check can be easily done with the brant package: https://cran.r-project.org/web/packages/brant/brant.pdf
