Computation of Gaussian orthant probabilities in high dimension
WebWe study the computation of Gaussian orthant probabilities, i.e. the probability that a Gaussian variable falls inside a quadrant. The Geweke---Hajivassiliou---Keane (GHK) algorithm (Geweke, Comput Sci Stat 23:571---578 1991, Keane, Simulation ... WebThe GHK algorithm (Geweke, Hajivassiliou and Keane) is an importance sampling method for simulating choice probabilities in the multivariate probit model. These simulated probabilities can be used to recover parameter estimates from the maximized … lancewood address george
