Abstract: We demonstrate that the probit weight function is U-shaped on R, i.e., it is decreasing on (infinity,0), strictly increasing on [0,infinity), and strictly convex on R. Knowledge of the shape of the probit weight function can resolve any confusion that may arise from a result in the classic paper of Sampford (1953).
