Hi Rick, Thank you so much for your post. While I have a question regarding the random samples generated from interpolation. I employed your code to generate random samples like 100 times (sample size is around 20000) for a logistic regression model in order to simulate the distribution of KS index. The interesting thing is that after round 20 times, all the following samples are pretty much the same although I utilize different seeds fro different sample.. It is a little bit weird from randomness perspective.
