The weighted average proportion variance was calculated with the R/Bioconductor package 'pvca' (version 1.0.0) [ 23].
A weighted average proportion for each outcome with the associated 95% CIs were provided using a logistic regression with intercept only model.
The variance component T (developmental stage/time) was the major source of variation in PC1 and PC2, and also explained a large proportion (weighted average proportion of 80.56%) of total transcriptional variance.
The weighted average proportion of genes tested in these thirteen multi-gene studies considered by their authors to exhibit allelic imbalance or statistically significant cis sequence effects is 26.2% (unweighted average is 25.7%).
The largest source of variability in fiber transcriptome was the variance component L (the near-isogenic lines; weighted average proportion of 56.4%), whereas the variance component E (environmental factor) explained 13.8% of the total transcriptional variance.
Therefore, excluding 60015, the mass-weighted average proportion of plagioclase in FAN samples drops to 93% (Wieczorek et al. 2006).
Combined indicators for all sites were then generated by aggregating site specific sampling results; the estimate of the mean was a weighted average of the proportion at each site weighted by the sample proportion (i.e., the number of patients selected divided by the total number of eligible patients at each site).
This is equivalent to calculating a weighted average of the proportion eligible for each intervention that receives the intervention, where the weight applied to each proportion is the ratio of the number eligible for the specific intervention to the sum of the numbers of eligibles for all interventions.
For the base case we took into account the age-specific probabilities of RVGE in the age group of children less than 5 years old and calculated a weighted average of the proportion of families in which both parents were working (31%).
In particular, since unskilled workers shifted out of agriculture into construction and other services over the last decade, the demand index for unskilled workers is dominated by a weighted average of the proportion of each of these industry's shares of unskilled labor, where the weights are, essentially, the growth rates of employment in the respective industries.
