摘    要：

We derive likelihood ratio (LR) tests for the null hypothesis of equivalence 
that the normal means fall into a practical indifference zone. The LR test can 
easily be constructed and applied to k > 2 treatments. Simulation results 
indicate that the LR test might be slightly anticonservative statistically, but 
when the sample sizes are large, it always produces the nominal level for mean 
configurations under the null hypothesis. More powerful than the studentized 
range test, the LR test is a straightforward application that requires only 
current existing statistical tables, with no complicated 
computations.
