Control Chart Constant d4 / D4

Description

Calculate D4 control chart constant from Wheeler's SPC books. These are in the same help file because of a quirk of how R generates help file names, but they are different constants with different uses.

Usage

spc.constant.calculation.D4(sample.size, n.sigma = 3)

spc.constant.calculation.d4(sample.size)

Arguments

sample.size

A scalar or vector of sample sizes

n.sigma

How many standard errors to use (default 3 for most control charts)

Value

A scalar or vector with computed constants.
