Conditional means of the dependent variable in a double-selection model: The roles of diet and exercise in body weight
We derive the conditional means of the dependent variables and their marginal effects in a dual ordinal selection model with log-transformed and untransformed dependent variables. Results are applied to a body mass index equation with endogenous diet and exercise treatments.
