ProcessCapabilityR
0.1.0Classical and Generalized Process Capability Indices
Overview
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) doi:10.1080/00224065.1986.11978984, Chan, Cheng & Spiring (1988) doi:10.1080/00224065.1988.11979102, Pearn, Kotz & Johnson (1992) doi:10.1080/00224065.1992.11979403, Kotz & Johnson (2002) doi:10.1080/00224065.2002.11980119, Montgomery (2020, ISBN:978-1-119-39930-8), Juran (1974, ISBN:978-0-07-033176-1), Harry & Schroeder (2000, ISBN:978-0-385-49437-2), and the AIAG SPC Reference Manual (2005, ISBN:978-1-60534-026-3).
