Dear @timbergquist and L3C Support, I am reaching out with a question regarding model robustness to missing data. Today during office hours, you mentioned that not all information available in the training data will be available in the test data (I apologize if I?m misquoting). Will the holdout test data include an equivalent covariate set to the censored training data? In other words, should our models be robust to individual missing values, or should they be robust to entire covariates (columns) being missing in the test data? Thanks so much for your time and help. Best, Zach
