DTI analysis - what do rate and prob actually mean

Scouse — Fri, 09 Jun 2023 00:57:34 GMT

Hello,

Could someone please explain or show me where I could find what rate and prob mean in this DTI, please?

I have attached a screenshot of the DTI.

Thanks in advance

Partition actually has two rates; one used for training that is the usual ratio of count to total, and another that is slightly biased away from zero. By never having attributed probabilities of zero, this allows logs of probabilities to be calculated on validation or excluded sets of data, used in Entropy R-Square.

In the Partition platform, for categorical responses, Rate is the same as "Prob" in the Distribution Platform, and "Prob" is a slightly biased weight.

This is definately confusing.
