Webimportant difference from the Gamma distribution as well as the absence of analytical expressions for the estimation of all its parameters motivates our search for efﬁcient algorithms to estimate inverse gamma distributions. The most traditional approach considered to estimate the parameters of a distribution is the Method of Moments (MM). WebMethod of Moments for Estimation by Hao Zhang In statistics, the method of moments is a method of estimation of population parameters such as mean, variance, median, etc. (which need not be moments), by equating sample moments with unobservable population moments and then solving those equations for the quantities to be estimated. skip frames youtube

WebJul 11, 2024 · Method of Moments. Because the mean of this distribution is μ = α θ and its variance is σ 2 = α θ 2, you can get a method-of-moments estimator (MME) of θ as θ ˇ = 336.9411 / 30.534 = 11.03495. So λ ˇ = 1 / θ ˇ − 0.09062118 and α ˇ = X ¯ / θ ˇ = 30.534 / 11.03495 = 2.767027. (As suggested in the comment by @Sycorax.)
