Web24 apr. 2024 · We start by estimating the mean, which is essentially trivial by this method. Suppose that the mean μ is unknown. The method of moments estimator of μ based on Xn is the sample mean Mn = 1 n n ∑ i = 1Xi. E(Mn) = μ so Mn is unbiased for n ∈ N +. var(Mn) = σ2 / n for n ∈ N + so M = (M1, M2, …) is consistent. WebThe classical method of moments, or simply method of moments, uses sample moments to estimate unknown parameters. For example, suppose a set of T observations, y1, . . . , yT are i.i.d. Poisson with intensity parameter . Since E[yt] = , a natural method to estimate the un-known parameter is to use the sample average, ˆ = T 1 XT t =1 yt (6.1)
