I have have already posted the following question: What numerical methods
are used in nlme to estimate correlation parameters?
I was referred to the Pinheiro and Bates book. Unfortunately, on p. 202,
section 5.1.1, under the title "Estimation and Computational Methods", no
description on a numerical method is provided. (When the data is
transformed to work with the profiled likelihood(y->ystar), one needs the
parameters that define Lambda. How are these parameters estimated?)
Any help is always appreciated,
Harlan
