Estimation biases for coefficients ${\mathit{\beta }}_1$, ${\mathit{\beta }}_2$, and ${\mathit{\beta }}_3$ (Panel A), as well as cumulative baseline hazards at times 0.6 and 1.2 (Panel B) over 100 Monte Carlo simulations. $H_1\hspace{0.17em}=\hspace{0.17em}{\widehat{H}}_0(0.6)$ and $H_2\hspace{0.17em}=\hspace{0.17em}{\widehat{H}}_0(1.2)$. The dotted gray line shows the place where bias equals zero.
