  1. Parameter values were estimated by fitting equation (9) to the egg count data encoded in a binary fashion (positive or zero) using standard GLM procedures. Parameters refer to the following covariates: δ1: host age, δ2: the natural logarithm of female worm burden and δ3: the natural logarithm of female mean weight. Parameters significantly different from 0: * p-value < 0.05, ** p-value < 0.01, ***p-value < 0.001.
