Data from Age-Related Macular Degeneration (ARMD) clinical trial

datasets

Provides functions and datasets to support the book
by Galecki and Burzykowski (2013),
'Linear Mixed-Effects Models: A Step-by-Step Approach',
Springer. Includes functions for power calculations,
log-likelihood contributions, and data simulation
for linear mixed-effects models.
