Estimated regression parameters and standard errors of combined ecological host characteristics and specific MHC class II DRB alleles on tick infestation obtained by GLMM (Laplace approximation with month and year as random effects) and GEE (with autocorrelation factor of roost: correlation parameter α = 0.03±0.07, overdispersion scale parameter = 7.1). Averaged estimates of GLMM models with ΔQAIC<2 are shown (QAICbest = 182.9, overdispersion parameter of the full GLMM model = 4.57). N = 122.
