Table 2 summarizes the posterior estimates of the mixture parameters for all three proportion scenarios and variance cases.
Furthermore, computing variances explained in this way will never lead to negative variances or to order reversals between proportion mediated and variance explained as in the examples, and more generally, will not be asymmetric in its treatment of the direct and the indirect effect.
Proportions and variances of events defining risk (major bleeding) and benefit (thrombosis averted) were obtained through a meta-analysis and used to define beta distributions.
All calculations assumed the same sample proportions and measurement variance (expressed as standard deviations) in each group.
Based on the principal component analysis performed for these trust scales, a single factor with an eigenvalue of 1.76 and variance proportion of 59% was retained (interpersonal trust scale) and eigenvalues of no other principal components exceeded unity.
With the help of condition index and variance proportion, we found that collinearity existed between the constant and air pressure, the average temperature and maximum temperature, as well as minimum temperature and relative humidity.
The tab 'PCA variance and loadings' contains the SD, proportion of variance, and loadings of all principal components from the PCA analysis shown in Figure 7F.
A meta-analysis of proportions was conducted to obtain pooled estimates of proportions and their variances using a fixed or random effects model as described in Appendix 1.
Components of the sampling design (sampling weights, stratification and stages) were taken into account with the "survey" package of R® 2.9.0 software [ 30] to calculate the proportions and their variances.
Estimates and proportion of variance explained for the contribution of individual repeatability and year to overall variance in mating behaviour, with 95% credible intervals (CI).
