 1. Performance of an elliptical extreme quantile region estimator is compared to
 a competing extreme quantile region estimator based on halfspace depth [1].
-Relative errors for both estimators are computed for each simulation scenario,
-and the errors are saved in the directory `sim-data/errors/`. Additionally,
-directory `sim-data/` includes the following data for reproducibility:
-
-   - true quantile regions,
-   - estimates (elliptical and depth) and
-   - samples, from which the estimates are calculated.

 extreme quantile region estimator for estimation, and thus, estimated quantile
