Let §1, §2, ..., En be independently distributed from N(0,7), i.e. E[§:] = 0 and V[§;] = T (a) Find the Method of Moments estimator for 7, call it ÎMOM: (b) Find the Maximum Likelihood estimator forT, call it îMLe. Note that maximization of the Likeihood function L(T | §1, §2, . .. , §n) is equivalent to maximizing the log-likelihood function l(T | §1, §2, ..., §n) = ln L(t | §1, §2,..., En). Hint: it is important to write l(t | §1, §2, . .. , Em) as a function of T and not the standard deviation.

1. Let §1, $2, ..., §n be independently distributed from N(0, T), i.e. E[§;] = 0 and V[§] = T %3D (a) Find the Method of Moments estimator for T, call it ÎMOM- (b) Find the Maximum Likelihood estimator forr, call it îMLE: Note that maximization of the Likeihood function L(T | 1, $2, ..., En) is equivalent to maximizing the log-likelihood function l(T | §1, $2,..., En) = ln L(T | §1, §2, . .., En). Hint: it is important to write l(T | §1, $2, ..., En) as a function of T and not the standard deviation.
