%description
Implements a two-stage estimation approach for Cox regression using
five-parameter M-spline functions to model the baseline hazard. It allows
for flexible hazard shapes and model selection based on log-likelihood
criteria as described in Teranishi et al.(2025). In addition, the package
provides functions for constructing and evaluating B-spline copulas based
on five M-spline or I-spline basis functions, allowing users to flexibly
model and compute bivariate dependence structures. Both the copula
function and its density can be evaluated. Furthermore, the package
supports computation of dependence measures such as Kendall's tau and
Spearman's rho, derived analytically from the copula parameters.
