Table 5.

Coverage probabilities and average length of 0.95 confidence intervals, bias, and root mean square error (rMSE) for C_τ with τ = 10 and 15, based on 1000 of iterations for a working Cox’s model with (AGE, ER, GS), when the true model is (II) the log-normal regression model with AGE, ER and GS.
