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 … WebThe CRLB for any unbiased estimator of the target state T [xc k yc(t k), x,c ,v y,c] is : 1 CRLB(tref ) [FIM(tref)] = −.
