Hello,
This is a request to enable support for a Validation column for Fit Parametric Survival / Fit Model (Personality: Parametric Survival). Other Fit Model personalities (e.g., Standard Least Squares, Generalized Regression) have this option but Parametric Survival does not.
There is a workaround to support this through Generalized Regression using the Maximum Likelihood estimation method but supporting this in Parametric Survival would be more efficient.
Thanks and regards
