Consistency parameter in independence_test_method

[priamai]

I noticed that for example the CDNOD calls them:
indep_test: Independence test method function. Default: ‘fisherz’.
But FCI:
independence_test_method: Independence test method function. Default: ‘fisherz’.

I think we should unify all the methods to use the same keyword?
Cheers.

Yeah, this is definitely something on the list. We will improve the APIs shortly. Thanks for your suggestion!
