Earlier we noted that sample variability tends to underestimate the variability in the corresponding population. To correct for this problem we adjusted the formula for sample variance by dividing by n -1 instead of dividing by n. The result of the adjustment is that sample variance provides a m...
Large sample variances for the Jolly-Seber estimates from a mark-recapture experiment are usually estimated by replacing unknown parameters by their estimates in the variance formulae obtained by the so-called delta method. These variance estimates are subject to large biases for small and moderate ...

(sometimes called historical estimator2); the modified Cornish-Fisher estimator V@R^αCF; and the classical Gaussian estimator V@R^αnorm, which is obtained by inserting mean and sample variance into the value-at-risk formula under normality: V@R^αemp(x):=−(x(⌊h⌋)+(h−⌊h...

When you take multiple samples from a population, each of those samples will (probably) have different statistics: a slightly different mean orstandard deviation/variance. The MVUE is the statistic with the lowest variance. There isn’t a simple formula to find the MVUE, and it may not actu...
