Calculate Capability Measures - Cp

Description

Calculate Cp, a measure that compares specification spread with observed process process spread. Higher values indicate that more process 'widths' can fit into the specification limits. This measure does not identify whether a process is 'targeted' within the specification limits.

Usage

spc.capability.cp.simple(
  lower.specification,
  upper.specification,
  process.center = NA,
  process.natural.tolerance
)

Arguments

lower.specification

Lower specification limit (if applicable)

upper.specification

Upper specification limit (if applicable)

process.center

Estimate of process center, used if specification limits are one-sided

process.natural.tolerance

Estimate of process natural tolerance

Value

A scalar with computed Cp.
