Table 5:

Proportion of times each covariate is selected across the four models fitted on simulated survival times from a Weibull PH model. The column “Coefficient” denotes the true coefficient value used in the simulations, multiplied by the corresponding covariate’s standard deviation. The column “× Time” is the proportion of times the HARE non-PH model selected an interaction between the covariate and time.
