Probably density from soerp

[Padarn]

Hi there,

I was just wondering if there is an easy way to use the result of soerp operations as random variables. For example

x=N(0,1)
y=N(1,2)
z=x+y

Then, can I get the pdf of z easily?

EDIT: Actually I see now (from a plot message) that this is not yet possible.

Did you have anything in mind about how you might go about doing this? Something like edgeworth expansions?
