Paper:

Fernandez, C., Chen, C.S., Gaillard, P. and Silva, A. (2024). Experimental Comparison of Ensemble Methods and Time-to-Event Analysis Models Through Integrated Brier Score and Concordance Index. arXiv preprint arXiv :2403.07460.

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.
