In the Probit Model Pr(Y = 1 | X₁, X₂

Multiple Choice

A) the ?'s do not have a simple interpretation.
B) the slopes tell you the effect of a unit increase in X on the probability of Y.
C) ?₀ cannot be negative since probabilities have to lie between 0 and 1.
D) ?₀ is the probability of observing Y when all X's are 0
