Dear all,
I have a question about the output of linear mixed model fitted in R
using nlme package. In particular, what are the t-values that are given
in an output, how are they calculated and based on what test? I guess it
cannot be a simple Student t-test, otherwise how can the simple Student

Dear all,
I have a question about the output of linear mixed model fitted in R
using nlme package. In particular, what are the t-values that are given
in an output, how are they calculated and based on what test? I guess it
cannot be a simple Student t-test, otherwise how can the simple Student
t-
The workers=as.factor(workers) codeline in my post dropped below my name. It
should be in the code before the command line for the linear model.

Wen, to follow up on Thierry, your workers are nested in machines (since each
worker only works one machine). Consider fitting a nested model. Though,
with few observations, you might run into the same problem. Further, if you
have observation triplets, and you expect systematic differences betwee

Hello,
I wanted to fit a linear mixed model to a data that is similar in
terms of design to the 'Machines' data in 'nlme' package except that
each worker (with triplicates) only operates one machine. I created a
subset of observations from 'Machines' data such that it looks the
same as th
