Since 1958 (BoxMuller), 50 years ago, people gave up to simulate normal deviations by adding uniform r.v.. This is how much Richard Ulrich is outofdate. Meanwhile he persists to misdirect people in Statistics regardless our corrective /advisory remarks. en.wikipedia.org/wiki/Box?Muller_transform  41k

Re: log normal? Posted: Dec 27, 2012 2:11 PM 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
