GL5PPFName:
The standard form of the Hosking generalized logistic distribution has the percent point function:
The general form of the Hosking generalized logistic percent point function can be obtained from the relation
<SUBSET/EXCEPT/FOR qualification> where <p> is a variable, number or parameter in the range (0,1); <alpha> is a number or parameter that specifies the value of the first shape parameter; <loc> is a number or parameter that specifies the value of the location parameter; <scale> is a number or parameter that specifies the value of the scale parameter; <y> is a variable or a parameter (depending on what <p> is) where the computed generalized logistic type 5 ppf value is stored; and where the <SUBSET/EXCEPT/FOR qualification> is optional. The location and scale parameters are optional.
