Share 'Computation of Weight of Evidence when either the number of bads or goods in a class of a variable is 0'
I want to understand the ways in which Weight of Evidence (WoE) is computed or adjusted in the following scenarios:
1. When number of goods in a class of a variable is 0
2. When number of bads in a class of a variable is 0
WoE = ln(distribution of goods/distributions of bads)
Scenario 1: WoE=ln(0) ?? when number of goods in a class =0.
Scenario 2: WoE=ln(distribution of goods/0)=ln(…
You can share this discussion in two ways…
