SUMMARY
The discussion focuses on finding the unique Minimum Variance Unbiased Estimator (MVUE) for lnQ, given that X(1)...X(n) are independent and identically distributed (IID) random variables following a Poisson distribution with parameter lambda=lnQ. The user proposes using T=sum(X) as a sufficient statistic and suggests that lnQ*=sum(X)/n serves as an unbiased estimator for lnQ. The conversation emphasizes the need to demonstrate that T is a complete statistic and to apply the Cramér-Rao lower bound to establish the MVUE's efficiency.
