spc.capability.cpm.simple(
  lower.specification,
  upper.specification,
  process.variability,

  nominal.center,
  n.sigma = 6
)

Arguments

lower.specification

Lower specification limit (if applicable)

upper.specification

Upper specification limit (if applicable)

process.variability

Estimate of process variability, expressed as variance

process.center

Estimate of process center

nominal.center

Nominal target for the process

n.sigma

The number of standard deviations to use in the denominator of the calculation. 6 is recommended, but 5.15 has also been historically used by Automotive Industry Action Group (AIAG).

Value

A scalar with computed Cpm.
