Detailed Description

Represents the dependence between X and Y in p(x | y), where (x,y) is a bivariate normal.

We need five parameters to determine a bivariate normal: three elements of the covariance matrix of the joint (var_X, var_Y, * and cov_XY) and the two means (mean_X, mean_Y). From these parameters, we can determine p(x | y) for any value of y.

Additionally, one can provide the conditional variance directly, which means one wants the mean to be simply y.
