Logistic Regression: ReplaceUnknowns has no attribute function #1075

Closed ajdapretnar closed 2 months ago

What's wrong? Logistic Regression reports "Fitting failed. ReplaceUnknowns has no attribute function."

The issue must be Statistics, but looking at the data there's nothing suspicious. So I am reporting here, because I believe LR doesn't handle certain form of the Corpus. Same issue with Random Forest, AdaBoost, KNN, SVM, SGD, GB. CN2 fails with an error.

How can we reproduce the problem? Corpus (bookexcerpts) - Statistics - Logistic Regression

What's your environment?

Did this ever work (in older version)?

TBH, I don't think so.
