Understanding Geometric Distribution and Sampling from a Known Distribution Under a Rejection Criterion The problem presented in the Stack Overflow post revolves around generating a target number of samples from a distribution, specifically the geometric distribution, under a rejection criterion. The goal is to produce N observations excluding zeros (0) while maintaining the same conditions as the original distribution, defined by the mean (mu) and size (size). This problem can be approached using two-stage sampling or theoretically through understanding the properties of the geometric distribution.
