WebMay 13, 2024 · A Poisson distribution is a discrete probability distribution. It gives the probability of an event happening a certain number of times ( k) within a given interval of time or space. The Poisson distribution has only one parameter, λ (lambda), which is the mean number of events. The graph below shows examples of Poisson distributions with ... WebSolution Step 3: Compute the CRLB and ﬁnd MVU From the Fisher information, CRLB is this case is simply var[θˆ(Y)] ≥ θ = 1 I(θ). To ﬁnd an MVU estimator, let’s try θˆ(y) = y. Since Y is Poisson, we have E{ˆθ(Y)} = θ. So θˆ(y) is an unbiased estimator of θ. Since Y is Poisson, we also have var{θˆ(Y)} = θ. So θˆ(y ...
