In the hippocampus, serotonin concentration had significant effects on the interaction of the variables MDMA dose × WIN dose [F 4,46) = 2.828; p < 0.03].
5-HIAA levels had significant effects on the interaction of the variables MDMA dose × WIN dose [F 4,44) = 3.271; p < 0.01].
Thus cooperativity, by itself and in conjunction with suitable restrictions on the interactions of the variables, does impose restrictions on the extent to which certain combinations of chaos-like properties are possible in a Boolean network.
Furthermore, we analyzed these factors by logistic multivariate analysis to assess the joint effects and interactions of the variables on lymph node involvement.
The effect of tree species identity and block, as well as their interaction, on the measured variables was tested using ANOVA.
The PERMANOVA test revealed effects of the habitat group, the year and their interaction on the dependent variables (Table 2).
A full factorial analysis was performed to evaluate the effect of each factor (fly ash and immersion age) and their interaction on the response variable (which was ASR-induced expansion).
We built a series of nested models to test the effects of site, region of origin, population, and population × site interaction on the response variable most closely associated with evolutionary fitness: fruit number.
The ANOVA was employed for the determination of significant variables and all their possible linear and quadratic interactions on the response variables.
Effects of habitat, pollination treatment (natural and supplemental), and their interaction on the two reproductive variables were tested using the lmer function of the 'lme4' package and a Gaussian error distribution.
