Hello! First of all, thank your for provide us with such an amazing software!

I would like to understand how cut-off plots are made with Jamovi? What is the method used for it?

I am trying to find an optimal cut-off value for an exercise related to a diagnostic test. For this reason, I am using "Binomial Logistic Regression" and the "Cut-off plot" option given by Jamovi inside the last menu called "Prediction".

With this option, the system plots sensitivity and especificity curves, but I do not know why the scale in X axis goes from 0 to 1. I was expecting to have, in X axis, the corresponding scale for the continuous variable in which I am searching for a cut-off value... So that, please, if you can help me to understand how Jamovi does this graphic I will be very grateful!

Thanks in advance!
