WebJan 15, 2010 · The simplest way to estimate the negative binomial parameters is by the method of moments. By equating the sample mean and the sample variance S 2 to the corresponding population mean μ and population variance σ 2 =μ+μ 2 /φ and calculating the solutions with respect to μ and φ one can get: (2) Where: In statistics, the method of moments is a method of estimation of population parameters. The same principle is used to derive higher moments like skewness and kurtosis. It starts by expressing the population moments (i.e., the expected values of powers of the random variable under consideration) as functions of the parameters of interest. Those expressions are then set equal to the sample moments. The number of such equations is the same as the numb… WebDec 28, 2024 · parameter of binomial distribution using the method of moments and derive t he joint asymptotic normality in Theorem 3. 1 of Section 3.
