LEXPPFName:
with denoting the shape parameter. Note that if < 1, then 0 < p < 1. This distribution can be generalized with location and scale parameters in the usual way using the relation
with and denoting the location and scale parameters, respectively.
<SUBSET/EXCEPT/FOR qualification> where <p> is a number, parameter, or variable in the interal (0,1]; <y> is a variable or a parameter (depending on what <p> is) where the computed logisticexponential ppf value is stored; <beta> is a number, parameter, or variable that specifies the shape parameter; <loc> is a number, parameter, or variable that specifies the location parameter; <scale> is a positive number, parameter, or variable that specifies the scale parameter; and where the <SUBSET/EXCEPT/FOR qualification> is optional. If <loc> and <scale> are omitted, they default to 0 and 1, respectively.
