Subject: R code/package for calculation of Wasserstein distance between two densities
In-Reply-To: <20150418220626.7dfa9e3976764f8a01a121b2@inbox.com>
Hi Ranjan:
Try this:
library(sos)
findFn("Wasserstein")
It appears there are three packages that might be relevant:
HistDAWass, transport and TDA.
HTH,
Dennis

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.
