spc.capability.cp.simple: Calculate Capability Measures - Cp

In burrm/lolcat: Miscellaneous Useful Functions

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.
