Calculate Capability Measures - Non-Normally Distributed Data

Description

Calculate capability measures and potential out of specification parts per million.

Usage

spc.capability.summary.ungrouped.nonnormal.simple.R(
  stat.lsl = NA,
  stat.target = NA,
  stat.usl = NA,
  stat.lsl.capability = stat.lsl,
  stat.target.capability = stat.target,
  stat.usl.capability = stat.usl,
  stat.lsl.performance = stat.lsl,
  stat.target.performance = stat.target,
  stat.usl.performance = stat.usl,
  process.center.capability = NA,
  process.center.performance = NA,
  process.variability = NA,
  process.n.upper = NA,
  process.n.lower = NA,
  process.n = NA,
  process.ppm.upper = round(1e+06 * process.n.upper/process.n),
  process.ppm.lower = round(1e+06 * process.n.lower/process.n),
  natural.tolerance = NA,
  p.lower = NA,
  p.upper = NA
)

Arguments

stat.lsl	Lower specification limit (if applicable)
stat.target	Target for process
stat.usl	Upper specification limit (if applicable)
stat.lsl.capability	Lower specification limit (if applicable) for capability measures
stat.target.capability	Target for process for capability measures
stat.usl.capability	Upper specification limit (if applicable) for capability measures
stat.lsl.performance	Lower specification limit (if applicable) for performance measures
stat.target.performance	Target for process for performance measures
stat.usl.performance	Upper specification limit (if applicable) for performance measures
process.center.capability	Estimate of process center for capability measures
process.center.performance	Estimate of process center for performance measures
process.variability	Estimate of process variability, expressed as variance. Used for performance measures only.
process.n.upper	Observed count above upper specification limit, used to calculate PPM (parts per million).
process.n.lower	Observed count below lower specification limit, used to calculate PPM (parts per million).
process.n	Total count of subjects/objects, used to calculate PPM (parts per million).
process.ppm.upper	Observed parts per million (PPM) above upper specification limit.
process.ppm.lower	Observed parts per million (PPM) below lower specification limit.
natural.tolerance	Natural tolerance estimate. Used for capability measures.
p.lower	Fit distribution area below LSL.
p.upper	Fit distribution area above USL.

Value

A data frame with computed measures.
