The UU-test for statistical modeling of unimodal data
作者:
Highlights:
• We propose UU-test that is a new method for deciding on dataset unimodality.
• The method attempts to approximate the empirical cdf of the dataset using a cdf that is piecewise linear, unimodal and models the data sufficiently.
• A unique feature is that the method also provides a statistical model of a unimodal dataset in the form of a uniform mixture model.
• The method can be employed in various data analysis tasks (e.g. clustering) where deciding on dataset unimodality is important.
