Key Influencers chart saying wrongly probability increases while it decreases
- 7 years ago
Hi,
After several hours trying to get a sample that did the same I found that I included a variable in the explain by field from another unrelated dataset. Without this field it says it doesn´t find any influencers, but by adding it suddently starts to find influencers but giving wrong trends.
My mistake, but maybe it would be better to return an error o not finding anything instead of giving wrong insights.
By the way, is there any documentation of which algorythms it uses and if it does any outlier exclusion, how it handles unbalanced datasets, overfitting etc..
Thank you
