WebBoth gre, gpa, and the three indicator variables for rank are statistically significant. The probit regression coefficients give the change in the z-score or probit index for a one unit change in the predictor. For a one unit increase in gre, the z-score increases by 0.001. For each one unit increase in gpa, the z-score increases by 0.478. jeroboam 1 king of israelWeb25 lug 2024 · Tobit models are a form of linear regression.
