| Jul 10, 2014 at 22:55 | comment | added | usul | I wonder if something is lost by thinking of $d$ as a metric on distributions rather than on random variables. In particular, as defined in the original post, when $i=j$ I think we have $d_{ij} = 0$. The point being that even if $i$ and $j$ have equal distributions, they are not equal as random variables (if they are independent). So it really would be a metric. | |
