abstract: Provides an R interface to the Python package 'u-stats' <https://pypi.org/project/u-stats/>
  for efficient computation of higher-order U-statistics using Einstein summation
  notation, implementing the methods of Chen, Zhang, and Liu (2025) <https://doi.org/10.48550/arXiv.2508.12627>.
  The package automatically converts R objects to 'NumPy' or 'PyTorch' tensors via
  'reticulate' and supports GPU acceleration when 'PyTorch' with 'CUDA' is available.
  Python dependencies are declared via 'reticulate' and can be installed automatically
  on first use. Designed for large-scale statistical estimation where numerical stability
  and performance are critical.
