Tests for the homogeneity of risk estimates across strata were based on a weighted sum of the squared deviations of the stratum-specific log-odds ratios from their weighted mean (Rothman and Greenland, 1998).
Similarly, the RMSE of the NBS map (24.1 Mg ha-1) was comparable with the mean standard deviation of the biomass strata (16.9 Mg ha-1) reported by [20].
Similarly, the RMSE of the NBS map (24.1 Mg ha-1) was comparable with the mean standard deviation of the biomass strata (16.9 Mg ha-1) reported by [ 20].
Using this scheme plots are allocated according to n h ~ N h S h, where h indexes strata, n h represents stratum sample size and N h and S h represent stratum population size and standard deviation of timber volume respectively (Cochran 1977).
The upper part of stratum CPEDC3 is lost.
However, the explosion experiments can clearly describe the stratum and attitude of stratum (e.g. Fig. 13(b)).
β-catenin, was relatively strongly expressed in cells of stratum basale and stratum spinosum (Figure 2C).
D is the average depth of the stratum boundary, and h(x') is the deviation of the boundary from the average.
Within strata, cell means were standardized with respect to the mean and standard deviation of the group of residents that neither received antidepressants nor had a chart diagnosis of depression.
"Standard deviation of 14.4 points?
