WebIn the univariate setting a distribution function (d.f.) F is unimodal with mode m if F is convex in (-∞, m] and concave in (m, ∞).Hartigan & Hartigan (1985) proposed the DIP statistic for testing whether a distribution is unimodal against a general multimodal alternative. The dip of a d.f. F is defined to be the maximum difference between F and the unimodal … WebThe Annals of Statistics. Hartigan & Hartigan's dip test for unimodality. For X ~ F i.i.d., the null hypothesis is that F is a unimodal distribution. The alternative hypothesis is that F is multimodal (i.e. at least bimodal). distribution. use for computing the p-value.

The first only computes Hartigan's dip statistic. diptest computes both the statistic and the p-value. The p-value can be computed using interpolation of a critical value table (default) or by bootstrapping the null hypothesis. Note that for larger samples (N > 1e5) this is quite compute and memory intensive.
