Description: Computes classical process capability indices (Cp, Cpk,
        Cpu, Cpl, Cpm, Cpmk, Pp, Ppk, Ppu, Ppl, Z) and the generalized
        process capability index Cpy (Maiti, Saha & Nanda, 2010)
        <doi:10.1080/16843703.2010.11673233> for any continuous or
        discrete quality characteristic. Users supply the probability
        density function (PDF) and cumulative distribution function
        (CDF) of the characteristic, and the package returns point
        estimates, bootstrap confidence intervals (percentile and BCa),
        and sensitivity tables/plots across ranges of short-term
        standard deviation (sigma), long-term standard deviation (s),
        desired yield (p0), and significance levels. Classical indices
        are recoverable as special cases under the normal distribution.
        The package follows the theory and notation of Kane (1986)
