Computes the ith iteration for computing the
squared imprecision estimates.
Description
This is an internal function that computes the ith iteration for computing the
squared imprecision estimates.
Usage
sigma_mle(i, s, sigma2, sigma.mu2, beta.bars, N, n)
Arguments
i |
Iteration i.
|
s |
Variance-covariance N x N matrix.
|
sigma2 |
Estimated imprecisions for each method in an N vector
|
sigma.mu2 |
Estimated process varinace.
|
beta.bars |
Estimates or hypothesized values for the N betas.
|
N |
No. of methods.
|
n |
No. of items.

Details
See Jaech p. 185-186 equations 6.3.1 - 6.3.6.
Value
