Hello !
I want to test the parallelism between two 4pl curves but I do not understand what the difference is between the F test and the Chi square test? The F test provides a p-value that is superior to 0.05 while the chi-square test does the opposite. I assume I cannot just pick one.

I was also wondering if it was possible to include the variability due to the random error when analysing 4 pl curves with the equivalence test.
Thank you for your response !
