But even after controlling for rank, the gap persists.
We excluded other alternative hypotheses to exchanging meat for sex, by statistically controlling for rank of the male, age, rank and gregariousness of the female, association patterns of each male-female dyad and meat begging frequency of each female.
The effect of Age on Mating Success residuals (controlled for Rank) was not significant (GLMM: linear, F1,4 = 0.01, P = 0.93, R2 = 0.0007).
In this study, we were able to control for predeployment rank, since all responders were recruits at baseline, but future longitudinal studies could examine how quickly Marines are promoted to further investigate this relationship.
The present findings challenge the idea that absolute metrics drive friendship choices by showing that a relative metric, one's perceived rank, remains a strong predictor of friend-rank after controlling for benefits, frequency of contact, and similarity.
Results of ANCOVA on change in number of symptoms controlling for age (mean centered), sex, rank, race, marital status, education, branch, duty, and smoking status revealed that the effect of time 1 cluster membership was significant [ F 1, 379) = 31.84; p < 0.001] (Table 3).
*By the Wilcoxon sign-rank test controlling for clustering by person, the difference between the two sequences were not statistically significant (p = 0.9306).
*Overall, IW fs sequence demonstrated the lesions to a larger extent than DESS sequence (Wilcoxon signed-rank test controlling for clustering by person, p < 0.0001).
*Overall, DESS sequence demonstrated the lesions to a larger extent than IW fs sequence (Wilcoxon signed-rank test controlling for clustering by person, p < 0.0001).
To evaluate H1, we will fit a Poisson random effects model, with the number of incident NSIs reported by each police officer, under the surveillance system, as the outcome variable, log (length of time spent under each condition pre-PEP and post-PEP) as an offset variable to account for the time spent at risk for an NSI, while controlling for possible confounders (eg, district, gender, rank).
Controlling for its income per person, China ranks 10th.Some sceptics of China's trade point out that many of its seemingly sophisticated exports include valuable imported components.
