WebFigure 1 – Bivariate normal density function. Observations about Mahalanobis Distance. Suppose X has a multivariate normal distribution. For any constant c, the set of points X which have a Mahalanobis distance from μ of c sketches out a k-dimensional ellipse. The value of the probability density function at all these points is the constant WebMay 21, 2024 · 6. Since the independent Metropolis-Hastings algorithm is formally valid, the issue stands in an inadequate calibration of the proposal to reach the entire support of the target (mixture) distribution. I just modified the code by choosing a larger variance matrix. sig=5*matrix (c (4, 1/2*2*2, 1/2*2*2, 4), nrow=2) ran the chain 10⁵ iterations ...
