Normally, what I've seen people do is that, if you have enough data, you take 1/3 of the data to worm up the model, then the rest of the data, I would divide in half for calibration and validation.

Dear allI am searching for information related with model calibration and validation. My specific doubts are partitioning of a given data set for calibration and validation purposes. For example if I have 20 data how many should I use for calibration? Does any body know of rules for this purpose?Thanks,Juan Pablo Monzon, Argentina
