Calculate D5 control chart constant from Wheeler's SPC books.
spc.constant.calculation.D5(sample.size, n.sigma = 3, negative.as.NA = T)
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.
