U mean statistics
In statistical theory, a U-statistic is a class of statistics that is especially important in estimation theory; the letter "U" stands for unbiased. In elementary statistics, U-statistics arise naturally in producing minimum-variance unbiased estimators. The theory of U-statistics allows a minimum-variance unbiased estimator to be derived from each unbiased estimator of an estimable parameter (alternatively, statistical functional) for large class… Web25 Aug 2024 · What does μ mean in probability? the mean of Here x represents values of the random variable X, μ is the mean of X, P(x) represents the corresponding probability, and …
