PLNCDFName:
where is a shape parameter, p is a shape (power) parameter, and and are the cumulative distribution function and the probability density function for the standard normal distribution, respectively. If p is 1, this distribution reduces to the lognormal distribution.
where <x> is a nonnegative number, parameter, or variable; <p> is a positive number, parameter, or variable that specifies the power parameter; <s> is an optional positive number, parameter, or variable that specifies the shape parameter; <y> is a variable or a parameter (depending on what <x> is) where the computed powerlognormal cdf value is stored; and where the <SUBSET/EXCEPT/FOR qualification> is optional. If the <s> parameter is omitted, it defaults to 1.
LET X2 = PLNCDF(X1,POW,SD) LET X2 = PLNCDF(X1,1,0.5)
where loc and scale are the location and scales parameters, respectively.
