Since 1958 (Box-Muller), 50 years ago, people gave up to simulate normal deviations by adding uniform r.v.. This is how much Richard Ulrich is out-of-date. Meanwhile he persists to misdirect people in Statistics regardless our corrective /advisory remarks. - 41k

In detail with the algebra. Normal N comes from U1 + U2 + ... + Uk . Log normal -log(N) comes from log(U1) + log(U2) + ... + Uk whichh implies N comes from U1 * U2 * ... *Uk. There may be differing weights for the different Uniform measures being added, but none of them overly influence it. -- Rich Ulrich
