RM 9.4 feedback (official release) : Costs/Benefits calculation
First thanks you for implementing the costs/benefits calculus in this new release - I think lot of users (including me) waited for this new feature.
2 months ago I had several questions in this thread about the Costs/Benefits calcultation and thanks to @IngoRM to answer me, that's was clear :
But in this official release , I'm seeing that "Total Cost/Benefit (expected) and the associated average were abandoned. My first question is why ?
The "Total Cost/Benefit (expected)" and the associated average are replaced by :
- "Total for best option"
My second question is : can you explain how this 2 numbers are calculated (despite my efforts i was not able to retrieve them) and why these 2 new numbers are more relevant than the "Total Cost/Benefit (expected)" ?
Here my attempt to retrieve these 2 numbers with the Titanic Dataset with all options by default in AutoModel with NB model :
Third question : in the new column called "cost" why the cost is not counted as negative when the prediction is wrong (I suppose the following cost matrix as the following) :
Thanks you for your listening,
