I'm sorry, but in the previous mail there was some "stupid" errors.
The assuption are:
x~N(mu,varx)
u~N(0,varu)
w=x-u
and so w~N(mu,varx+varu)
I must verify that the integral of the following function in the domain
of the X
1/(sqrt(2*pi)*sqrt(varu))*exp(-.5*((x-w)/sqrt(varu))^2)
equals to 1.
Thank you in advance.
