In estimation theory and statistics, the Cramér–Rao bound relates to estimation of a deterministic parameter. The result is named in honor of Harald Cramér and Calyampudi Radhakrishna Rao, but has als
Illustration of the Cramér–Rao bound: there is no unbiased estimator which is able to estimate the (2-dimensional) parameter with less variance than the Cramér–Rao bound, illustrated as standard deviation ellipse.

Cramér–Rao bound
…and statistics, the Cramér–Rao bound (CRB) relates to estimation of a deterministic (fixed, though unknown) parameter. The result is named in honor of Harald Cramér and Calyampudi Radhakrishna Rao, but has also been derived independently by Maurice Fréchet, Georges Darmois, and by Alexander Aitken and Harold…
