We compared the sequence of estimators \( \bs S^2 \) with the sequence of estimators \( \bs W^2 \) in the introductory section on Estimators. Thus, computing the bias and mean square errors of these estimators are difficult problems that we will not attempt. For the normal distribution, we'll first discuss the case of standard normal, and then any normal distribution in general. The result follows from substituting \(\var(S_n^2)\) given above and \(\bias(T_n^2)\) in part (a).

We know for this distribution, this is one over lambda. The parameter \( r \), the type 1 size, is a nonnegative integer with \( r \le N \).
1.12: Moment Distribution Method of Analysis of Structures D) Normal Distribution. So, rather than finding the maximum likelihood estimators, what are the method of moments estimators of \(\alpha\) and \(\theta\)? Here's how the method works: To construct the method of moments estimators \(\left(W_1, W_2, \ldots, W_k\right)\) for the parameters \((\theta_1, \theta_2, \ldots, \theta_k)\) respectively, we consider the equations \[ \mu^{(j)}(W_1, W_2, \ldots, W_k) = M^{(j)}(X_1, X_2, \ldots, X_n) \] consecutively for \( j \in \N_+ \) until we are able to solve for \(\left(W_1, W_2, \ldots, W_k\right)\) in terms of \(\left(M^{(1)}, M^{(2)}, \ldots\right)\).
