WebThe bivariate normal distribution is the exception, not the rule!. It is important to recognize that "almost all" joint distributions with normal marginals are not the bivariate normal distribution. That is, the common viewpoint that joint distributions with normal marginals that are not the bivariate normal are somehow "pathological", is a bit misguided. Web22.1.3 Stan Functions.
