Abstract
The properties of likelihood ratio tests and simpler t-tests are investigated by simulation under an assumed beta-binomial model for parameter values typically found in toxicological studies. It is found that likelihood ratio methods are a least as powerful as the simpler approaches and in certain situations can be significantly more powerful.This publication has 4 references indexed in Scilit:
