Software

  1. clusterpval is an R package that computes valid p-values for a difference in means between estimated clusters in a data set. [website] [paper] [github]
  2. multiviewtest is an R package for learning whether and how clusters defined with respect to different data views are associated. [paper1] [paper2] [cran]
