title: 'mmtdiff: Moment-Matching Approximation for t-Distribution Differences'
version: 1.0.0
doi: 10.32614/CRAN.package.mmtdiff
abstract: Implements the moment-matching approximation for differences of non-standardized
  t-distributed random variables in both univariate and multivariate settings. The
  package provides density, distribution function, quantile function, and random generation
  for the approximated distributions of t-differences. The methodology establishes
  the univariate approximated distributions through the systematic matching of the
  first, second, and fourth moments, and extends it to multivariate cases, considering
  both scenarios of independent components and the more general multivariate t-distributions
  with arbitrary dependence structures. Methods build on the classical moment-matching
  approximation method (e.g., Casella and Berger (2024) <https://doi.org/10.1201/9781003456285>).
