www.stata.comprobit model for the first equation, and the second log corresponds to running the univariate probit for the second model. If ˆ= 0, the sum of the log likelihoods from these two models will equal the log likelihood of the bivariate probit model; this sum is printed in the iteration log as the comparison log likelihood.

services.math.duke.eduA standard bivariate normal distribution is a bivariate normal distribution where the means of both coordinate variables are zero and the covariance matrix is the identity matrix. You can use the fact that any linear combination of random variables following a multi-variate normal distribution has a normal distribution. Let [Z 1 Z

For the standard bivariate normal, if the variables are uncorrelated (that is, if ˆ= 0) then the joint density factorizes into the product of two N(0;1)

If we have a response category with fewer than five observations, then we should combine it with another category. The chi-square test statistic is simple to implement in Stata. In fact, we have been doing it all along! Each time we use the tabulate command with
