Weban AE with Hartigan’s Dip-test of unimodality [14]. The Dip-test is a parameter-free statistical test that returns a Dip-value within the interval (0,0.25], which specifies the multimodality of a one-dimensional data set. Dip-values close to 0 indicate unimodality of the input samples, while larger values indicate that the samples WebTitle Hartigan's Dip Test Statistic for Unimodality - Corrected Description Compute Hartigan's dip test statistic for unimodality / multimodality and provide a test with …
