spc.constant.calculation.D3 | R Documentation |
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.
spc.constant.calculation.D3(sample.size, n.sigma = 3, negative.as.NA = T)
spc.constant.calculation.d3(sample.size)
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. |
A scalar or vector with computed constants.
