Description: Fit Cox non-proportional hazards models with time-varying
        coefficients. Both unpenalized procedures (Newton and proximal
        Newton) and penalized procedures (P-splines and smoothing
        splines) are included using B-spline basis functions for
        estimating time-varying coefficients. For penalized procedures,
        cross validations, mAIC, TIC or GIC are implemented to select
        tuning parameters. Utilities for carrying out post-estimation
        visualization, summarization, point-wise confidence interval
        and hypothesis testing are also provided. For more information,
        see Wu et al. (2022) <doi: 10.1007/s10985-021-09544-2> and Luo
        et al. (2023) <doi:10.1177/09622802231181471>.
