BLUPS from lme models

Patrick Connolly-4
The bottom of page 276 of the "Gold Book" Modern Applied Statistics by
Venables and Ripley, 4th edition, the last sentence states:

"Random effects are set either to zero or to their BLUP values."

Am I correct in inferring from that, it amounts respectively to
removing the random term from the model, or setting it as a fixed
effect?  To get something meaningful, one needs to choose which random
effects are relevant to the topic under study?

Thank you.

No.

But as this is a statistical issue and not an R programming issue, it is
off topic here. Post on stats.stackexchange.com or other statistical list
and/or spend time with web tutorials.

Cheers,
Bert
