difficult to compute (as in unbiased estimation of standard deviation); because a biased estimator may be unbiased with respect to different measures of

In statistics and in particular statistical theory, unbiased estimation of a standard deviation is the calculation from a statistical sample of an estimated

statistical theory related to the problem of optimal estimation. While combining the constraint of unbiasedness with the desirability metric of least variance

In statistics, best linear unbiased prediction (BLUP) is used in linear mixed models for the estimation of random effects. BLUP was derived by Charles
