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 … WebAs a beginner, you do not need to write any eBPF code. bcc comes with over 70 tools that you can use straight away.
