Abstract
In this paper, we investigate change-point problems for the number of modes in circular data. We use a mixture of two circular normal distributions to model the observed data. Tests for detecting the presence of change-point are derived using the generalized likelihood-ratio method. Asymptotic distributions of the test statistics are obtained. Results of some simulation studies are also presented.
