WebIn probability theory and statistics, the exponential distribution or negative exponential distribution is the probability distribution of the time between events in a Poisson point process, i.e., a process in which events occur continuously and independently at a constant average rate. It is a particular case of the gamma distribution. WebApr 23, 2024 · If h(X) is a statistic then varθ(h(X)) ≥ ( d dθEθ(h(X)))2 nEθ(l2(X, θ)) The following theorem give the third version of the Cramér-Rao lower bound for unbiased estimators of a parameter, specialized for random samples. Suppose now that λ(θ) is a parameter of interest and h(X) is an unbiased estimator of λ. Then varθ(h(X)) ≥ (dλ / dθ)2 …
