process.sd | R Documentation |
This function computes the process standard deviation and is used internally by the function precision.grubbs.ncb.od.
process.sd(x)
x |
A matrix or numeric data.frame consisting of an n (no. of items) by N (no. of methods) matrix of measuremnts. |
The process standard deviation is the standard deviation of the true values uncontaminated by measurement error. See Jaech, p. 185.
A scalar containing the method of moments estimate of the process standard deviation.
