Hi Jasp team! I am not sure if this is a bug or not, but I made a Q-Q plot and a P-P plot of a simple dataset in which I have the numbers 1-5 each 5 times. The Q-Q plot looks like this:
and the P-P plot like this:
Note that in the Q-Q plot, the sample quantiles are correclty put equal to the values with the same score (1s, 2s, etcetera), but the theoretical quantiles are instead ordered in a sequence. In the P-P plot this is the other way around, and now theoretical values that are equal are assigned the same cumulative probability but the sample values are ordered. Is this expected?
