As I could not get the expected result at first, I checked the solution workflow and found the difference.

After putting the difference to my workflow, the output matched.

But I sill do not understand what it means.

Could somebody help me?

I also used a Logistic Regression for comparison!
The best day is Saturday, earlier in the day and closer to the location with the coefficient analysis!
