I'm not sure which one of the results is correct, but I trust the mathematica one more. There should be only one lognormal distribution, I think there's no disambiguation. The documentation of the R package didn't help me. It would be interesting what other computer algebra systems say, but I don't have any. $\endgroup$ –

LogNormalDistribution [μ, σ] represents a continuous statistical distribution supported over the interval and parametrized by a real number μ and by a positive real number σ that together determine the overall shape of its probability density function (PDF). Depending on the values of σ and μ, the PDF of a lognormal distribution may be either unimodal with a single "peak" (i.e. a …

By definition, X = e Z has a Lognormal distribution with pdf f ( x): f [x_, mu_, s_] = (1/ (x s Sqrt [2 Pi]))*Exp [- ( (Log [x] - mu)^2/ (2 s^2))]; In your case, the variance-covariance matrix has zero correlation, so (given Normality) your two variables are in fact independent.

Mar 07, 2011 · Just as (by the central limit theorem) the sum of a large number of independent, identically distributed random variables is nearly normal, the product of a large number of independent, identically distributed random variables is nearly log normal. The red vertical line marks the mean of the distribution. Contributed by: Chris Boucher (March 2011)

The lognormal distribution is sometimes called the Galton distribution, the antilognormal distribution, or the Cobb – Douglas distribution. LogNormalDistribution is the distribution followed by the logarithm of a normally distributed random variable. In other words, if is a random variable and (where denotes "is distributed as"), then .
