We drop all of the cases for which y is not ... Webmedian of the distribution). If x= θ, then f(x) = 0. The case where θ= 0 and m= 1 is called the standard lognormal distribution. The case where θequals zero is called the 2-parameter lognormal distribution. The equation for the standard lognormal distribution is \( f(x) = \frac{e^{-((\ln x)^{2}/2\sigma^{2})}}
