Hi Rick,

Thank you for this timely blog. I am working on a model calibration problem and had to implement isotonic regression to 'smooth' the predicted probabilities. I replicated your methodology and works great.

However, when trying your TRANSREG test with monotone transformation, the results do not respect the monotonic nonincreasing (or decreasing) constraint. I assume based on the comments above some monotonicity constraints need to be explicitly specified. Would you be able to point me to some examples on how to specify these constraints from product documentation or maybe from your past blogs? Thank you!
