Abstract

In this report, we derive the test on partial parallelism in profile analysis. Parallelism hypothesis, along with the other two hypotheses which are the level and the flatness , has been studied by others. We focus mainly on a specific case of parallelism hypothesis, where the profiles are parallel up to a point and then divert from each other. The test statistics for two different scenarios will be presented.
