Understanding Rejection Sampling method by Valentina Alto

WebThe Rejection Sampling method is usually used to simulate data from an unknown distribution. To do this one samples from a distribution that covers the suport of the unknown distribution and use certain criteria for accepting/rejecting the sampled values. One way to do this is as follows (Rice, p 92). Step 1: Generate T with density m.
