Often people loosely say 'distribution' when they mean 'density' ... and mostly that looseness causes no problem since it's clear from context. So it's quite correct to refer to those CDFs as 'marginal distributions'. They are! | |
| Jan 30, 2015 at 19:47 | comment | added | Henry E | I'm not sure there's a difference but the context in which "marginals" is often used is in referring to the cumulative distribution functions of the individual random variables themselves. Which is not quite the definition on the wikipedia page of marginal distributions, hence my slight confusion. | |
