but y is type of factor

Hi Thomas,

I am getting zero information value for many variables having low observation count. I was getting significant IV value using 'Information' package in R for these variables. What is the cutoff for minimum observation count to get non-zero IV value in this package? Is it minimum 5% observations in each bucket?

Regards,
Ishan

I have used this package successfully a few times. I have never gotten this error before. What could be the cause? I am sure that my response variable is binary and I am only getting this error with numeric observations when I use the iv.mult() function.
