R help - Oct 2008 - Mallows' distance or Earth Mover's distance in R?

Hi

I am looking for an implementation (or alternative to) Mallow's
distance or the Earth Mover's distance to compare distributions or
unnormalized distributions (signatures).

Is there an implementation in R or can somebody recommend an alternative?

Thanks

Rainer

Hi Rainer,

we have not implemented the Mallow's distance so far. Out package 
distrEx includes implementations of the Hellinger, the Kolmogorov, the 
total variation and the Cramer von Mises distance. Combined with our 
package distrMod one can compute minimum distance estimators.

?MDEstimator
