To establish the mathematical equivalence between standard cubic spline regression and the restricted least-squares estimator.
Derived a formal mathematical proof showing the equivalence of cubic spline regression and restricted least-squares estimation under shared restrictions.
Applied both estimation procedures to an empirical benchmark dataset previously evaluated using spline regression.
Standard cubic spline regression mathematically simplifies to a special case of the restricted least-squares estimator.
Restricted least-squares framework provides greater analytical flexibility regarding parameter constraints and hypothesis testing options.
