Conditional on the interaction with deprivation, the association between absolute change in NHS allocation and change in mortality amenable to healthcare was approximately linear (test for non-linearity: P=0.16, see regression diagnostic in supplementary appendix 3).
A conditional power approach is used to prevent inflation of the overall trial type I error rate while maintaining adequate statistical power conditional on the statistically significant interaction.
The size of the competitor's gene network and the rate of recombination, conditional on interactions with the rate of environmental change (dE/dt), accounted for 79% of the variance in the focal species' dN/dt during the first 20 generations of competition (Table 1).
A t test for each reported eQTL assessed significance of the interaction conditional on the v-eQTL, epistasis SNP and the eQTL.
In addition, the standard deviations of the resulting distributions conditional on the independent variables (protein physical interaction degree, toxicity degree, TATA box, number of TFs) differed widely, making the linear model for the variance invalid.
The robustness of these organisms was computed and an analysis of variance showed that, consistent with previous work [ 27, 28], high mutation rates tended to favor the evolution of robustness (P < 0.001), whereas population size had no direct effect on robustness (P = 0.818), but and indirect one conditional on mutation rate (interaction term, P < 0.001).
In particular, Crowley considered conflict strategies that were conditional on interactions in previous conflicts with the same opponent.
Other schemes are obviously possible and some of them are explored in [13], including ε-interactions and resampling conditional on the effective sample size.
Phenotypic variance differs conditional on the genotype at a locus involved in an interaction.
The effects of some of these alleles will also be conditional on interactions with other alleles and environmental factors such as salt loading.
