Logical regression comparison with R

    I have previously noticed other problems with the logistic regression operator, as noted in the following thread: https://community.rapidminer.com/discussion/47835/logistic-regression-operator-and-weights#latest
    I am not sure why that thread was closed without any apparent resolution, or whether that issue is related to the issue that you have highlighted here.
    @mschmitz have you looked into the performance of the logistic regression operator and noticed any of the issues described in these threads?

    Hi,
    Please note that we updated the H2O backend for 9.7. This may change results.
