Sentence examples for calculation of variance from inspiring English sources
Standard results for the calculation of variance estimates and corrected degrees of freedom using multiple imputations (Little and Rubin 2002) apply directly to analyses using PVs.
Calculation of variance components confirmed that 'within-sponge' variation in Cd, Zn, Cu, Pb and Se concentrations were low (1 14%) relative to the two largest spatial scales (49 98%) examined.
Table 1 shows permeability data and similar depths and Table 2 shows division of permeability data into three zones for well A. Equations (2)–(4) are used for calculation of variance between zones, variance in each zone, and zonation coefficient, respectively.
Further details of sampling weights and calculation of variance have been previously reported [5].
However, the calculation of variance components for fixed and random effects would be identical, despite this difference in interpretation [18], [19].
The percentage of the variance contributed by each source of variation for ethanol yield was estimated by calculation of variance components (Table 2).
The conventional calculation of variances [12] only measures the absolute values of the differences between instantaneous values and the mean values (DBIMs).
To improve the performance of aggregation, two factors need to be considered in the calculation of variances: (1) it is necessary to distinguish between positive and negative values of DBIM; (2) wind speed fluctuates continuously, which incurs continuous changes under operational conditions of wind turbines, so DBIMs at different time must be distinguished from each other.
12 In order to extend beyond estimation of the mean and make formal inferences, both the Lin 1997 and Bang-Tsiatis methods allow for the calculation of variances.
35 When tables contained cells with a value of 0, we added 0.5 to these cells to allow the calculation of variances.
The methodology also permits easy calculation of posterior intervals, whereas the calculation of variances for posterior probability estimates from multilevel logistic models in a frequentist setting would have been enormously difficult.
