Description: Tools for fitting generalized competing event (GCE) models
        and estimating covariate effects on omega-plus, the ratio of
        the hazard for an event of interest to the hazard for a
        competing event, on both the cause-specific (Cox) and
        subdistribution (Fine-Gray) hazard scales. Confidence intervals
        and p-values are obtained from the Lunn-McNeil (1995) stacked
        (augmented) data approach. The package builds GCE risk scores
        from the model linear predictor, identifies risk-score
        cutpoints that maximize the separation in omega-plus between
        groups, and produces cumulative incidence ("alligator") plots
        by risk group and calibration plots of predicted versus
        observed omega-plus. Methods follow Carmona et al. (2014)
