To make this estimation one gets where represents the marginal variance of noisy observations and.

For the estimation of the marginal variance of noisy observations, in [5] the following relation is proposed: (9).

In [5] the marginal variance of the th coefficient is estimated using neighboring coefficients in the region, a squared shaped window centered on this coefficient with size.

This estimator requires prior knowledge of the noise variance and of the marginal variance of the clean image for each wavelet coefficient.

Another very important parameter of the bishrink filter is the local estimation of the marginal variance of the noise-free image.

The parameters in (8) have been chosen to imply a marginal variance of (y_{t}) equal to one and to resemble the values usually encountered in real empirical applications; see, for instance, Hentschel (1995) and Bollerslev and Mikkelsen (1999).2.2

The marginal variances of the PCB concentrations (log transformed) and the cord blood mercury concentrations (log transformed) are approximately equal, so the two exposure indicators have about the same reliability ratio if the log10 PCB) measurement error variance is assumed to be 0.02 (i.e. a coefficient of variation of on PCB).

The two-stage estimator of the pooled exposure effect β is a weighted average of the β ^ k, weighted by the inverse marginal variances of the β ^ k, denoted w k = (σ ^ k 2 + σ b 2 ) − 1. Thus: (6) β ^ = (∑ k w k β ^ k ) / ∑ k w k (7) var = (∑ k w k ) − 1 Two methods [ 100] are frequently used to estimate the random effects variance σ 2 b in equations 6 and 7.

Diagonal elements in the variance matrix are estimates of marginal variances for all estimated parameters, and are denoted by for the estimated parameters in the model.

The estimator of the pooled exposure effect is a weighted average of the individual study estimators, weighted by the inverse marginal variances; the marginal variance is the sum of the individual study-specific variances and the variance of the random study effects.

Dolphins can detect the most marginal variance in an object's size and consistency – assessing even the molecular difference between a sheet of copper and aluminium.
