WebDec 18, 2024 · If the average of many realizations is less than the CRLB, there is a problem but any single realization can beat the CRLB $\endgroup$ – user28715 Dec 17, 2024 at 22:03 WebNov 27, 2024 · Published. 27 November 2024. Given a statistical model X ∼ Pθ with a fixed true parameter θ, the Cramér–Rao lower bound (CRLB) provides a lower bound on the variance of an estimator T (X). The CRLB is useful because if an unbiased estimator achieves the CRLB, it must be a uniformly minimum–variance unbiased estimator …

Webknown as the Cram´er-Rao Lower Bound (CRLB) for the variance of an unbiased estimator of φ(θ.) (3) An estimator whose variance is equal to the CRLB is called a most efficient estimator The efficiency eff(φˆ) of an unbiased estimator φˆ of φ(θ) is defined to be the ratio eff(φˆ) = CRLB Var(φˆ) Note that 0 ≤ eff(φˆ) ≤ 1 for ... WebFor chaotic systems with state-dependent gradient square (Type-II systems), the EKF-based method is found to have a smaller MSE. The averaged Cramer-Rao lower bound (CRLB) is introduced here as a performance measure. It is shown that the EKF-based method approaches the averaged CRLB for both Type-I and Type-II systems when noise level is …
