Dear Readers: I have two issues in nonparametric statistical analysis that i need help: First, does R have a package that can implement the multimodality test, e.g., the Silverman test, DIP test, MAP test or Runt test. I have seen an earlier thread (sometime in 2003) where someone was trying to write a code for the Silverman test of multimodality. Is there any other tests that can enable me to know how many modes are in a distribution? Second, i would like to test whether two distributions are equal. Does R have a package than can implement the Li (1996) test of the equality of two distributions? Is there any other test i can use rather than the Li test? Thank you in advance for your help.
