WebJul 18, 2012 · Hartigan’s dip statistic (HDS) For the HDS measure, we used p values resulting from Hartigan’s dip test. Thus, HDS values range from 0 to 1, with values less than .05 indicating significant bimodality, and values greater than .05 but less than .10 suggesting bimodality with marginal significance. WebHence, the dip measures proposed by Hartigan and Hartigan [7] is as a test statistic for unimodality. Hartigan [6] obtained a Fortran code and then Maechler provided corrected …
