B1. A random sample of n observations, Yi, ..., Yn, is selected from a pop- ulation in which Yi, for i-1,2,..., n, possesses a common distribution the same as that of the population distribution Y (a) Suppose that we know Y has a Geometric distribution with parameter p, p unknown. Find the estimator using the method of moments. C3. Continue with Problem B1 (a), Homework 2. Find the MLE of p.
previously, the problem b1(a) is Suppose that we know Y has a
Geometric distribution with parameter p, p unknown. Find the
estimator p using the method of moments.
BUT, in this problem, THE QUESTION IS: FIND THE MLE OF P.
