title: 'gpci: Generalized Process Capability Indices and Bootstrap Confidence Intervals'
version: 0.1.0
doi: 10.32614/CRAN.package.gpci
abstract: 'A comprehensive, generalized framework for computing, estimating, and validating
  Generalized Process Capability Indices (GPCIs). Supports user-supplied probability
  density functions (PDF/PMF), cumulative distribution functions (CDF), survival functions
  (SF), and quantile functions with uncensored data parameter estimation via Maximum
  Likelihood Estimation (MLE). Provides classical and non-normal capability indices,
  including Cpy (Maiti, Saha and Nanda, 2010) <https://doi.org/10.1080/16843703.2010.11673233>,

  indices. Computes parametric and non-parametric bootstrap confidence intervals at
  90%, 95%, and 99% confidence levels using percentile, normal, basic, BCa, BCp, and
  studentized bootstrap methods. Evaluates Highest Posterior Density (HPD) intervals
  and Heidelberger-Welch convergence diagnostics. References: Maiti, Saha and Nanda
