Recall that the bivariate normal distribution was used to model the joint distribution of annual storm peak X (millimeters/day) and annual rainfall amount Y (millimeters). The article used the following values as estimates of the distribution's parame tersH 147 mm/day, ?,-59 mm/day, ?.-223 mm, @y-: 117 mm, and ? .67.
