I am still not getting it.
I am trying to understand multivariate distributions and copulas. In the beginning of
each article it is said that the observed data must be transformed to uniform or
frechet distribution by means of probability integral transform. Apparently this is
something easy and trivial and a standard procedure in introductory statistics. Well,
I have some books in statistics of different degrees of complexity but unfortunately I
cannot find the answer there. All examples are only about how to generate a random
sample with desired (always exponential) distribution.
Now, I have two variables X and Y and I want to transform them to Frechet or uniform.
I was just thinking, if this is so simple and trivial as all stat books say, then, it
must exist a simple function for it in R.
P.s. @Rolf, I would like to have it as a homework but I am afraid I am too old for a
school.

Is this a homework question?
cheers,
