Hi,

thank you for the tutorials. Can you please help me with the permutation_test? I always get this error:

` File "/var/folders/q4/g502v5zj32x0gmls_36j_9280000gn/T/ipykernel_55912/2957162646.py", line 5, in permt = pls.permutation_test(X, Y, 100)

Hi, Thanks for your interest. I will need a few more details to debug and find out whats wrong. Would it be possible to send an example script and some test data to replicate the issue to pychemometrics_at_gmail.com? Any data with similar structure (number of columns/rows) in X and Y or with same number of columns but less rows in case its too large.
