In estimation theory and statistics, the Cramér–Rao bound (CRB) expresses a lower bound on the variance of unbiased estimators of a deterministic (fixed, though unknown) parameter, the variance of any such estimator is at least as high as the inverse of the Fisher information. Equivalently, it expresses an … See more The Cramér–Rao bound is stated in this section for several increasingly general cases, beginning with the case in which the parameter is a scalar and its estimator is unbiased.

WebCramér-Rao Bound¶ The Cramér-Rao Bound is a fascinating result. If we just start by thinking of estimators as functions of the data that try to estimate the parameter, you might imagine that there if you work really … WebDec 18, 2024 · I applied MATLAB's interpft function (which I assume should be unbiased), and I also get wildly changing variances, which after a couple of runs approach 1, although I feel that since the Cramer-Rao constitutes a lower bound, it should be impossible for the variance to go below it. d\u0026d logo svg
