Package: eVCGsampler 1.1.2

Andreas Schulz

eVCGsampler: VCG Sampling using Energy-Based Covariate Balancing

Provides a principled framework for sampling Virtual Control Group (VCG) using energy distance-based covariate balancing. The package offers visualization tools to assess covariate balance and includes a permutation test to evaluate the statistical significance of observed deviations.
