Let's hypothesize that I have n iid observations from a Poisson distribution with parameter lambda, how do I derive the method of moments estimator of lambda?
Let's hypothesize that I have n iid observations from a Poisson distribution with parameter lambda, how do I derive the method of moments estimator of lambda?
Here's what I have.
How do I simply this more?
First show that is the mean of a Poisson RV with parameter
Since the s are iid each with mean the sample mean of the s has expectation equal to
