The value of GCTA has recently been greatly increased by extending it beyond the univariate analysis of the variance of a single trait to the bivariate analysis of the covariance between two traits (Lee, Yang, Goddard, Visscher, & Wray, 2012).
As shown, discomfort contributed significantly to the prediction of the variance of OA, NAPB and VAB, beyond the residents' other characteristics that were statistically controlled in each regression equation.
This can potentially induce a lower-than-expected X-statistic for high counts and a correspondingly inflated p-value; however, the application of Coates' correction algorithm increases the variance of the counts beyond what would be expected for Poissonian data, so that this form of bias does not arise.
Further, this model explained an additional 4.3% of the variance in HbA1c (Δ R= 0.043, P = 0.001, total adjusted R=0.24), which indicated that chronotype contributed significantly to the model's explanation of the variance of HbA1c above and beyond demographic and sleep variables.
Note that the variance of cellular features does not increase beyond the thermal limits as compared to within the thermal range.
This would at least reduce the variance of the relative risk on days with temperatures beyond the OT.
The Women's March humor worked, too, because of the variance of tone on display.
It limits the variance of it," says Riggio.
Thus, the variance of the modulated bin-rate is the excess variance of the binned spike-count beyond the level expected from a homogeneous Poisson process.
Find the variance of these measurements.
