However, in contrast to the results observed for FSIQ, parental education did not significantly moderate the variance of VIQ in older males.
For differential expression analysis of the qPCR data in the cell lines xenografts comparison study, linear models were fit to each miRNA, and an empirical Bayes approach was applied to moderate the variance [ 36].
Alternatively, parental educational attainment level could also be a proxy of one's own adulthood educational attainment level, as such indirectly moderating the variance decomposition of cognitive ability in adulthood.
Reading comprehension significantly moderated the nonshared environmental variance in associating with antisocial friends, with increased variance at lower levels of reading comprehension and indication that common genetic influences contributed to higher reading achievement and better-behaved friends.
Antisocial friends significantly moderated the nonshared environmental variance in reading comprehension, with increased variation at lower levels of association with antisocial friends, with niche-picking indicated.
By modelling the effects of life events in young adult twins, Spatola et al. [19] recently found that adversities that take place within the childhood-adolescence window of risk moderate the genetic variance for CO2 sensitivity, as assessed by a CO2 challenge provocation test.
Even though the average branch length in the 52 taxa tree is moderate the variance of pairwise distances between sequences is higher when the tree contains more branches.
Now suppose that we want to investigate whether M moderates the variance decomposition of T, and rather than modeling this in a bivariate model (Fig. 1a), we choose to include M in the means model of T (Fig. 1b), such that we can study the moderation effects of M on the variance decomposition of the residual variance T′.
One such procedure is limma (Smyth, 2004), where an empirical Bayes model is used to moderate the probe-wise variances.
To moderate the impact of residual variance, probe signals for the LIS and NaCl extractions were averaged between replicates then assessed as a function of their position along the chromosome (Fig. 1B).
