corSpher

Re-exports <a href="/link/nlme%3A%3AcorSpher?package=pwr4exp&version=1.0.1" data-mini-rdoc="pwr4exp::nlme::corSpher">nlme::corSpher</a> from the nlme package.

Provides tools for calculating statistical power for experiments
analyzed using linear mixed models. It supports standard designs, including
randomized block, split-plot, and Latin Square designs, while offering flexibility
to accommodate a variety of other complex study designs.
