Description

This is an internal function that computes Grubbs' method of moments estimators of precision for the nonconstant bias model using original data values.

Usage

1
precision.grubbs.ncb.od(x, beta.bar.x = beta.bar(x))

Arguments

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 >= 3 and n > N.

beta.bar.x

Either estimates of beta or hypothesized values (one for each method in an N vector).

Details

See Jaech, p. 184.

Value

Grubbs' method of moments estimates of the squared imprecision (variances).
