Table 2.

Average weights for the individual models included in the stacked survival model for each of the six scenarios in Section 5.1 (Inline graphicInline graphic covariates, and Inline graphic censoring)

Stacked models Log-Normal Weibull Gamma
Linear effects Log-Normal 0.61 0.19 0.42
Weibull 0.23 0.45 0.37
Cox 0.14 0.31 0.19
RSF 0.02 0.05 0.02
Non-linear effects Log-Normal 0.34 0.12 0.27
Weibull 0.14 0.28 0.18
Cox 0.06 0.21 0.08
RSF 0.46 0.39 0.47

Each simulation is replicated Inline graphic times. ‘RSFs’ stand for random survival forests.
