Gamma density function
Webwhere the gamma function is defined as Γ(α) = Z ∞ 0 yα−1e−y dy and its expected value (mean), variance and standard deviation are, µ = E(Y) = αβ, σ2 = V(Y) = αβ2, σ = p V(Y). … WebIn probability theory and statistics, the negative binomial distribution is a discrete probability distribution that models the number of failures in a sequence of independent and identically distributed Bernoulli trials before a specified (non-random) number of successes (denoted ) occurs.
