Thanks a lot Robert!
Another detail is that if I define X1, X2, X3 and
X4 rv. iid. and I define y1=min(X1,X2) and
y2=min(X3, X4) in the way that y1 is independent of y22..
.. it is not possible to evaluate
CharacteristicFunction(Z,t); (with my computer it takes infinty time)
I thought that independence would help.. but not.

Yes. Only to start I could assume
s12=s11=s22=s21=5.. but I dont see how
to answer my questions even in this
simplied case.
Thanks for the comment.

Thanks again for the long comments and explanation
Jean-Marc.
I was trying in Mma Test1:= etc. Effectively,
Test1:= is a bunch of things. Nevertheless
they are used by a function (MyFormula1) like this:
MyFormula1[MyTest_, i_] := (( v[DeleteCases[#,
i]] ) & /@ Rest[Subsets[T]])
But what is not clear to me is how to obtain
your expressions like
MmaTranslator/Assign(T, [1, 2, 3]), MmaTranslator/Assign(v([]), 0),
I am not sure if that is input or output.
A last thing: I didnt know that was not possible
to translate programs..in fact.. I thought it was
easy.. given that apparently there is one option
to translate notebooks (which probably may contian
programs).
Anyway.. thanks for the comments

Yes Axel Vogt. It is a nice way to solve the problem.
My mistake was to use the 'expr' used by Roberto
Israel.

Hello Vogt,
Sorry for the interruption,
I was trying to implement your advice (below.. a copy past of the commands that you wrote)..but the
first message that I got is
"Error, expression sequences cannot be assigned to lists"
exaclty after the command
L[i]:=eval(E[i], x=%):
Could you tell me what is wrong?. I am using
Maple v10.. in Windows.
I will really appreciate your answer.
Jean

Thanks.. I use version 10. I think your advice work well.

Thanks a lot Scott por your post and for writing the correct expression of my problem.
When I tried to run what you advice I got the message:
Error, `plots` does not evaluate to a module
I only did use the copy + paste commands. Where may be my problem?
Thanks again,
Jean

Thanks a lot for the clarifications and suggestions.
The correct expression of my problem is below, in the message
Scott03 "The greater sign again".
I find really very useful your message, thanks a lot,
Jean
