OWEA - Optimal Weight Exchange Algorithm for Optimal Designs for Three
Models
An implementation of optimal weight exchange algorithm
Yang(2013) <doi:10.1080/01621459.2013.806268> for three models.
They are Crossover model with subject dropout, crossover model
with proportional first order residual effects and interference
model. You can use it to find either A-opt or D-opt approximate
designs. Exact designs can be automatically rounded from
approximate designs and relative efficiency is provided as
well.
