bartProbit - How does the action handle missing values in predictor variables?

Réponse

The 'missing' parameter controls this. The default is 'SEPARATE', which treats missing values as a distinct group. Other options include 'NONE' (excludes observations with missing values), 'MACBIG' (treats missing as the largest machine value), and 'MACSMALL' (treats missing as the smallest machine value).
