probability theory - Does there exist a mutivariate inverse?

Let F:RR be a distribution function (CDF)



In this case, we can define the inverse X of F, and it is a random variable on (0,1) such that FX=F.




Hence, every distribution (CDFs) can be viewed as the cdf of a random variable on (0,1).



Is there an analogous result for joint distribution functions (CDFs)?



That is, for a fixed n, does there exists a probability space (Ω,F,P) such that every joint distribution function F:RnR is FX for some n-dimensional random vector X on (Ω,F,P)?
