More on Multivariate Gaussians
Fact #1: mean and covariance uniquely determine distribution
Fact #3: closure under sum, marginalizing, and conditioning
covariance of conditional distribution is given by a Schur complement (independent of x_B. is that obvious?)

Relationships among probability distributions - Wikipedia
- One distribution is a special case of another with a broader parameter space
- Transforms (function of a random variable);
- Combinations (function of several variables);
- Approximation (limit) relationships;
- Compound relationships (useful for Bayesian inference);
- Duality;
- Conjugate priors.
