Hey guys, can you help me with the proofing of E(X) = r/p and Var(X) = rq/p^2
The discussion focuses on the negative binomial distribution, specifically the proof of the expected value E(X) = r/p and variance Var(X) = rq/p². The variables are defined as follows: X represents the number of trials until the r-th success, p is the probability of success on each trial, and q is the probability of failure, where q = 1 - p. Participants provide insights into the derivation of these formulas, emphasizing the importance of understanding the underlying concepts of the distribution.
