Withdrawal threshold measurements for two representative subjects from the postpartum-with-pups (red) and virgin females (green) groups exemplifying missing data and differences in timing of measurements. At several time points observations are available from one animal and not the other. The same two representative subject predicted trajectories are overlayed to show model fit.
