NettetIf the components of a Gaussian RV are pairwise independent, then they are independent. If W is standard Gaussian, and U is orthogonal matrix, then UW is also standard Gaussian RV. Canonical Representation of a centered Gaussian RV X with K XX = U UT, then X L= U˙1=2W with W standard Gaussian. From Gaussian to standard Gaussian: … Nettetfinancial applications, where Gaussian Processes can be used as well. That includes portfolio al-location, price prediction for less frequently traded stocks and non-linear clustering of stocks into their sub-sectors. In section 2 we begin with an introduction to the Bayesian non-parametric Gaussian Processes and
Nettet14. jun. 2024 · 2.3.2 Marginal Gaussian Distribution. The marginal distribution of a joint Gaussian, given as. p ( X a) = ∫ p ( X a, X b) d X b. is also Gaussian. It can be shown using the similar approach which is used for condition distribution above. The mean and covariance of marginal distribution is given as: E [ X a] = μ a. C o v [ X a] = Σ a a.
