Dear friends, Before reinventing the wheel, I was wondering if anyone can point me to code for calculating the Wasserstein distance between two densities. I am particularly interested in mixture densities (in functional form). I know that we have the earthmovers distance in R via the emdist package but it appears to me upon a quick look that this can not handle densities in functional form. So, I was wondering if anyone had any ideas on code for this problem. Many thanks and best wishes, Ranjan ____________________________________________________________ Can't remember your password?

R code/package for calculation of Wasserstein distance between two densities

Hi Ranjan:
Try this:
library(sos)
findFn("Wasserstein")
It appears there are three packages that might be relevant:
HistDAWass, transport and TDA.
HTH,
Dennis
