Hello, I have the normal random variables y(t)~N(mu, sigma.sq) and want to decompose them into n normal variables: y(t) = x(t,1) +
+ x(t,n)
x(t,i)~N(mu, sigma.sq/n) The problem is not as simple as can appear. All my experiments didn?t give me anything so far. Are there any tools to do this?
This should work, provided I understand the problem correctly: x <- rnorm(n,sd=sqrt(sigma.sq/n)) x <- x - mean(x) + y/n
