precision.grubbs.ncb.od {merror} | R Documentation |
This is an internal function that computes Grubbs' method of moments estimators of precision for the nonconstant bias model using original data values.
precision.grubbs.ncb.od(x, beta.bar.x = beta.bar(x))
x |
A matrix or numeric data.frame consisting of an n (no. of items) by N (no. of methods) matrix of measuremnts. N must be greater than 3 and n > N. |
beta.bar.x |
Either estimates of beta or hypothesized values (one for each method in an N vector). |
See Jaech, p. 184.
