Dear All: I need someone to clarify the value of the*meanlog*and*stlog*used in the function*rlnorm*when you sample from log-normal distribution. rlnorm(n, meanlog = 0, sdlog = 1) *For example: *y<- rlnorm(25, meanlog = 5, sdlog = 1) Is the value of the meanlog,*5*, the mean of the log-normal distribution. Similarly, is the value of the*sdlog*,*1*, the standard deviation of the log-normal distribution. or 5 and 1 are the mean and standard deviation of the normal distribution of x = log(y) ~N(mean =5, var = 1) with many thanks steve -- -- Steven M.
