e consider several random variables
given by the joint
distribution
For every variable
we
introduce
Suppose
is some uniform random variable supported on
.
Observe
that
Hence, the variable
is distributed as
for some
,
uniformly distributed on [0,1].
Therefore,
Summary
(Sklar theorem 1) Suppose the uniform on
random variables
are given by the distribution
.
Pick a set of non decreasing functions
and introduce the random variables
then
(Sklar theorem 1)
Summary
(Sklar theorem 2) Conversely, for any set of random variables
given by the joint distribution
the
expression
(Sklar theorem 2)
is a joint distribution for the random uniform on [0,1] variables
.
Here the functions
are marginal distributions of
