Local constant (LC) estimates and approximate 95% pointwise confidence intervals (CIs) for the effects of sex and Calgary vs Edmonton zone using a random sample of 2,000 subjects and their ED visits from the PMHC data. In each panel, the thick black curves denote the coefficient estimate and the corresponding 95% CIs using the reduced sample for missing birthdates with W=5 or W=100; the thick grey curve represents the estimate using the full data and associated 95% CIs (shaded); the dark grey dashed curves denote the estimate and the 95% CIs with the reduced sample and the known birthdates; the dashed line and the surrounding shade are the estimate and the 95% CIs under the Andersen-Gill (AG) model, respectively
