Control Chart Constant d3 / D3

Description

Calculate d3 or D3 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.D3(sample.size, n.sigma = 3, negative.as.NA = T)

spc.constant.calculation.d3(sample.size)

Arguments

sample.size

A scalar or vector of sample sizes

n.sigma

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

negative.as.NA

Logical - negative values are possible from the calculation, but not useful. Set to false to obtain negative values instead of NA.

Value

A scalar or vector with computed constants.
