rand_perm not working
When I try to run the shapely effects code on the ishigami function with n_perms = None
, I get the expected outputs. However, if I set n_perms to 6, which should trigger the use of random estimation method, the Shapley effects are almost equally distributed between all the features. I would expect that setting n_perms to 6 should give the same result as n_perms = None
. This makes me believe that your random estimation method is not working as expected.
