Equivalence trials

Here we will test the equivalence claim in a trial comparing two different methods to prevent depression relapse in high-risk patients. The delta is 11%. The analysis will use the two one-sided tests approach.

The dplyr and magrittr libraries and the relapse.trial dataset have been preloaded for this session.
