Hi,

I was searching the following by uncle google and in this forum and I didn't find anything that could help me.

I have a family of independent random variables with normal distributions: X, Y, Z, etc. The truncation (in my context) is:
Xt = { 0, if X(a)>0, X(a), if X(a)<=0 }
Now, according to this definition, I need to calculate the following:
mean( (( Xt+Y )t + Z)t )
where (X+Y)t means the truncation of the random variables sum and mean is the expected value. Of course, the summing will be iterated further.

I'm a beginner in Matlab and I've no idea how to solve it.

Thanks,

Pawel
