Description: Implements the adaptive influence-based borrowing framework 
    proposed by Qinwei Yang, Jingyi Li, Peng Wu, and Shu Yang (2026+) in the paper 
    ``Improving Treatment Effect Estimation in Trials through Adaptive Borrowing 
    of External Controls" <doi:10.48550/arXiv.2604.13973> for augmenting Randomized Controlled 
    Trials (RCTs) with External Control (EC) data. This package provides a 
    comprehensive workflow to: (1) quantify the comparability of external control 
    samples using influence scores approximated via the influence function of the 
    M-estimator; (2) construct candidate borrowing subsets and select the optimal 
    subset that minimizes the Mean Squared Error (MSE); and (3) calibrate systematic
    differences in external outcomes using R-learner methods implemented via 
    Ordinary Least Squares or Kernel Ridge Regression.
