Thanks Robert...another detail.....

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. Regards, Jean

and..assuming sij =5?...

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. Jean

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 Jean

yes..it works....

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

what may be the problem?...

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 a lot Scott...

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

Why I get this error?...

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

yes.. it was the greater sign.....

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
