An ANOVA was performed on each gene using the linear model above, and three contrasts based on differences between the two treatments for each individual region.
In contrast our method, using the linear noise approximation in combination with numerical optimisation, took 25 min to converge.
I'm using the linear method".
This analysis was initially performed for prenatal and postnatal Pb using a test for the linear contrast across quartiles, but without covariate control.
The discovery method leveraging interaction plots and the linear contrast can be used to scan pairs of predictors to quickly find potentially interacting predictors, and the 4-machine estimation method can be used to estimate the interaction effects for those interacting predictors.
All genetic effects are scaled relative to this F2 generation mean, thus the linear contrasts used to estimate the genetic effects are sometimes called F2 scaling tests.
In addition, a main effect of 'task load' was computed using a linear contrast to identify brain regions that showed magnetic resonance signal intensity variation correlated with task difficulty (van den Heuvel et al., 2005).
The RR for each cluster was estimated using linear contrast, and rate ratios plus 95% CIs were used to estimate the differences in annual mean moderate/severe exacerbation rates for each cluster.
We tested the dose-response effect using a modified linear contrast [ 25] in a mixed effects linear regression model that included random subject effects.
In post-hoc analyses, we evaluated the statistical significance of possible linear trend in the results for social class, education, and FH by using linear contrast in coefficients from stratified covariate-adjusted models and formulae were specific to each variable's number of levels (e.g. 5 for difficulty paying bills).
