I appreciate Don B's comments; it was a rookie mistake on my part. From the correlations and plots I generated to help me picture the situation, I fell into the trap of thinking about a "standard" bivariate normal distribution (if there is such an animal), much as I general

Not sure exactly what your after here, but the software program qs-STAT by Q-DAS has a useful 3D bi-variate ND plot that is developed from two data sets. I'll send you a image if you like. === This list is open to

. The domain of random variable X and Y is -1 X, Y 1, which is points in xy plane. The points is located clustring near origin (0,0), so I try to approximate the its density to bivariate normal distribution. Ah. That explains why (1 - sigma_max*sigma_min) would not be imaginary. It is still unclear
