I have a categorical variable Q1 taking the values from 1 to 4 and a binary variable Bad taking the values 1 and 0.
I want to calculate WoE and IV for the variable according to the existing categories in ascending order.
I know that HPBIN has option to calculate those statistics but it would also create other bins - i want to use the variable binned as it is. I have also tried to use the output of the Freq procedure, but it becomes inconvenient for the cases in which there is no events in some of the categories.
