Implements a two-stage estimation approach for Cox
regression.
Uses five-parameter M-spline functions for baseline hazard
modeling.
Provides model selection based on log-likelihood
criteria.
Initial CRAN submission.
splineCox 0.0.2
Fixed bugs in the splineCox.reg2 function when handling
custom numeric vectors.
Added examples for custom vector normalization in the vignette.
Improved documentation and error messages.
splineCox 0.0.3
New Features
Added plotting functionality to splineCox.reg1 and
splineCox.reg2 for visualizing the estimated baseline
hazard function with confidence intervals.
Updated the vignette to include descriptions and examples of the
plotting feature.
Documentation Improvements
Improved documentation for splineCox.reg1 and
splineCox.reg2 to clearly describe the new plotting
feature.
Updated the vignette to demonstrate how to use the plotting
functionality.

splineCox 0.0.4
New Features
Added a new function spline.copula implementing a
B-spline copula model based on the five-parameter M-spline basis
functions.
The copula function offers both copula density and distribution
function evaluations, with a variety of built-in coefficient matrices
(presets) for modeling a wide range of dependence structures.
Documentation and
Publication
The main methodology of this package, including the spline-based Cox
regression has been published in a peer-reviewed journal.
Updated documentation to reference the published article.
splineCox 0.0.5
Added analytical computation of Kendall’s tau and Spearman’s rho in
spline.copula()
Updated documentation and vignette accordingly
splineCox 0.0.6
Added spline.copula.simu() to report Kendall’s tau and Spearman’s
rho(empirical and theoretical).
splineCox 0.0.7
Fixed missing importFrom(stats, integrate)
Updated spline.copula.simu with improved functionality
splineCox 0.0.8
Changes
Updated the constraint tolerance used in
spline.copula() to 3e-4 to improve numerical
stability while maintaining estimation accuracy.
Added spline.copula.MLE() as a dedicated maximum
likelihood estimation routine for spline-based copula models, intended
for stable and reproducible estimation workflows.
