Local constant (LC) estimates and approximate 95% pointwise confidence intervals (CIs) for the effects of sex and Calgary vs Edmonton zone using the full PMHC data and the empirical birthdate distribution for missing birthdates. In each panel, the thick black curves denote the coefficient estimate and the corresponding 95% CIs for missing birthdates under the empirical distribution with W=5 or W=100; the thick grey curve represents the estimate for missing birthdates under a uniform distribution and associated 95% CIs (shaded); the dark grey dashed curves denote the estimate and the 95% CIs with the known birthdates; the dashed line and the surrounding shade are the estimate and the 95% CIs under the Andersen-Gill (AG) model, respectively
