The simulation section presents three experiments of simulated data and we simulate this data with three different techniques.

We used coxed library and simsurv library implemented in R.

Coxed Library

• coxed_numfeatures: the script used to generate the data of the decreasing number of features experiment.
• coxed_numsamples: the script used to generate the data of the increasing number of samples experiment.
• coxed_percensorship: the script used to generate the data of the increasing percentage of censorship experiment.

Simsurv Library

• simsurv_numfeatures: the script used to generate the data of the decreasing number of features experiment.
• simsurv_numsamples: the script used to generate the data of the increasing number of samples experiment.
• simsurv_percensorship: the script used to generate the data of the increasing percentage of censorship experiment.

Python Experiments

• python_numfeatures: the script used to generate the data of the decreasing number of features experiment.
• python_numsamples: the script used to generate the data of the increasing number of samples experiment.
• python_percensorship: the script used to generate the data of the increasing percentage of censorship experiment.

Ensemble Method

• PBC_ensemble_method: Implementation of our aggregation method to the PBC dataset.
