Hi,
Could there be a bug when a variable is actually decreasing the probability that it says it´s increasing it in the new Key Influencers chart?
The chart shows a decreasing trend when the variable increases, but the automated coment by Power BI say that it increases. Besides the chart I know that it should decrease the probability if the variable increases.
Solved! Go to Solution.
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
Hi @vdburg ,
Could you please share your sample data and excepted result to me so that I can test that by my side if you don't have any Confidential Information.Please upload your files to One Drive and share the link here.
