3.2.5 Negative Binomial Distribution - 國立臺灣大學
www.math.ntu.edu.tw3.2.5 Negative Binomial Distribution In a sequence of independent Bernoulli(p) trials, let the random variable X denote the trialat which the rth success occurs, where r is a fixed integer. Then P(X = x|r,p) = µ x−1 r −1 pr(1−p)x−r, x = r,r +1,..., (1) and we say that X has a negative binomial(r,p) distribution. The negative binomial distribution is sometimes defined in terms …
