Sentence examples for stratum variance from inspiring English sources

If we monitor the change in stratum variance, 64-station setup provides a stable stratum variance.

In other words, the decrease in stratum variance is expected to saturate through the iterations.

Stratum variance Q h versus number of iterations of the VQA.

(a) shows the mean stratum variance Q h at each iteration.

i.e., the stratum variance Q h for each stratum h is the average of the stratum variance Q hj for each time stamp j ranging from 1 to T. An alternative to the summation operation is to use dissimilarity measures.

For each stratum h, a dispersion measure called stratum variance, Q h is calculated: Q_{h} = sqrt{{n_{h}^{2}}times bar{upgamma}(A_{h}, A_{h})} (2).

The actual model parameters and stratum variances were estimated separately for each survey.

In this model σ2 h1 and σ2 h2 are the within stratum variances of OV and CC respectively and σ h12 is the within stratum covariance term.

The use of mixed models allows for the estimation of separate stratum variances thus providing a more complete description of the data (Gilmour et al. 1995).

The term R = diag(V 1, … V H ) represents the error structure, which is assumed to be a diagonal matrix with separate stratum variances, represented by V h where h indexes strata and H is the total number of strata.

For example, Neyman allocation is a method used to allocate samples based on the stratum variances and population sizes, assuming similar sampling costs in the strata, and given a fixed total sample size (Cochran 1977).
