Table 1.

Empirical relative bias of estimates of CE(28, j) from simulation study described in Section 4 for both scenarios. Bold entries correspond to estimates where the assumed β_j was correct. Relative bias of $\widehat{CE}(28,j;{\beta }_j)$ defined as $\{\widehat{CE}(28,j;{\beta }_j)-CE(28,j)\}/CE(28,j)$.
