abstract: Implements a moment-targeting normality transformation based on the simultaneous
  optimization of Tukey g-h distribution parameters. The method is designed to minimize
  both asymmetry (skewness) and excess peakedness (kurtosis) in non-normal data by
  mapping it to a standard normal distribution (Cebeci et al., 2026 <https://doi.org/10.3390/sym18030458>).
  Optimization is performed by minimizing an objective function derived from the Anderson-Darling
  goodness-of-fit statistic with Stephens's correction factor, utilizing the L-BFGS-B
  algorithm for robust parameter estimation. This approach provides an effective alternative
  to power transformations like Box-Cox and Yeo-Johnson, particularly for data requiring
  precise tail-behavior adjustment.
