Table 2.

Simulation results for Study 2; bias, standard deviation of estimates (SD), and percent coverage of nominal 95% confidence intervals (CR) of regression coefficients are compared for cumulative hazard functions estimated using the conditional intensity with those estimated using empircal rates, with and without missing data.
