Sentence examples similar to day variances from inspiring English sources

For these validations, the 'DNA isolation' and 'PCR day' variance components were calculated on the basis of an overall model.

The 'PCR' variance component was expected to be much larger than the 'DNA isolation' and 'PCR day' variance, but from Table  4 it can be seen that the factors 'DNA isolation' and 'PCR day' contribute substantially to the reproducibility.

In this way, it is possible to estimate how much the 'DNA isolation' and 'PCR day' variance components contribute to the total variance of the individual GMO analysis/real-time GMO detection methods.

In summary, daily enteric emission is principally constrained by the quantity and fermentability of the feed consumed; but an understanding of within-day and between-day variances is required to ensure the emission data collected reflects the long-term CH4 phenotype of a ruminant.

Day-to-day variance was defined as the variance in phthalate metabolite levels between samples 1 or 2 days apart, regardless of whether they were collected in cycle 1, 2, or 3. Cycle-to-cycle variance was defined as the variance between the three cycles minus the day-to-day variances within the cycles.

a, b, c: between-subjects, between-days, and within-day variance.

The aim of this study was to investigate the accuracy and precision of estimators of between-subjects, between-days and within-day variance components obtained by sampling strategies differing with respect to number of subjects, total sampling time per subject, number of days per subject and the size of individual sampling periods.

Mathiassen et al. [ 4] used bootstrapping to construct confidence intervals for the between-subjects variance, between-days variance and residual (within-day) variance in electromyography (EMG) data from cyclic assembly work.

The variables α i, β j i) and ϵ k(ij) are assumed to be independent and normally distributed with zero mean and variances σ 2 BS (the between-subjects variance), σ 2 BD (the between-days variance) and σ 2 WD (the within-day variance between 1-minute exposure values), respectively - for all i j and k.

As challenge variables, we used either the sum of milk yield or the accumulated fat-to-protein ratio of the first 3 test-days (<120 d in milk), pre-adjusted for herd-test-day variance.

In general, when block size increased, a stronger negative bias appeared for the within-day variance, and a stronger positive bias for the between-days variance (Table 3; illustrated in Figure 2).
