The author strongly encourages us to become proficient in manipulating Gaussian distributions using the techniques presented here as this will prove invaluable in understanding the more complex models presented in later chapters. WebAdding independent Gaussians Linear transformations Marginal distributions Conditional distributions Example Partition X into into X 1 and X 2, where X 1 2Rr and X 2 2Rs with r + s = d.

WebThe covariance in (2.88) is expressed in terms of the partitioned precision matrix given by (2.69). We can rewrite this in terms of the corresponding partitioning of the covariance matrix given by (2.67), as we did for the conditional distribution.
