model testing the differential-allocation hypothesis_table5

Data for the linear mixed-effect model testing the differential-allocation hypothesis based on observations of the proportion of female incubation in 283 out of 292 lasting monogamous pairs that initiated breeding. The dependent variable is the relative count of female versus male nest visit (FIDInc and MIDinc) records (using the ‘cbind’ function in R) within each pair. The random effects male and female identity (ID) reflect the individual repeatability across different partners (variance component V), while the random effect pair ID controls for overdispersion in the binomial counts. The predictor of interest (quality difference) is the difference in estimated quality between the partners (female PCA score minus male PCA score:diff_FM).
