WebMarginally Gaussian but not jointly Gaussian. Let X be a standard Gaussian. We define the random variable x if X <1, Y = -X if X > 1. (a) Show that Y is also standard Gaussian. (b) Argue that X + Y is not Gaussian; therefore, (X,Y) is … The probability content of the multivariate normal in a quadratic domain defined by (where is a matrix, is a vector, and is a scalar), which is relevant for Bayesian classification/decision theory using Gaussian discriminant analysis, is given by the generalized chi-squared distribution. The probability content within any general domain defined by (where is a general function) can be computed usin… elpa ドアホン 取り付け
