Description: Implements nonparametric and semiparametric methods for
        comparing two survival distributions under non-proportional
        hazards (non-PH) with right, left, and doubly censored data.
        The methods are based on the Receiver Operating Characteristic
        (ROC) curve length and its kernel-based estimate (Bantis et al.
        (2021) <doi:10.1002/sim.8869>) and the overlap coefficient
        (OVL) and its kernel-based estimate (Schmid and Schmidt (2006)
        <doi:10.1016/j.csda.2005.01.014>), as well as a new joint
        inference approach involving both the kernel-based ROC length
        and the kernel-based OVL. These methods do not require prior
        knowledge of the underlying non-PH pattern. The methods
        accommodate the "last is censored" phenomenon for
        right-censored data by using flexible parametric approaches
        only for the portion of the tail of the distribution that
        corresponds to time values beyond the last observed event (see
        Bantis et al. (2017) <doi:10.1002/sim.7394>). The analogous
        "first is censored" phenomenon is also accommodated for
        left-censored data.
