Parameters of lognormal pdf in blocksim

[susan]

Say I have a variable X which follows lognormal distribution. So log(X)=y follows normal distribution. In the Blocksim, which one the mean value required input for the vairable X: mean(X),ln(mean(X)), or mean(y)?

Many thanks.

The mean and the standard deviation of the lognormal distribution are the mean of the log of times and the standard deviation of the log of times
