GEEPPF

Name:
    GEEPPF (LET)
Type:
    Library Function
Purpose:
    Compute the standard form of the geometric extreme exponential percent point function with shape parameter gamma.
Description:
    The standard form of the geometric extreme exponential percent point function is:

      G(p) = LOG[(gamma/(1-p)) +1 - gamma]    0 <= p < 1; gamma > 0
Syntax:
    LET <y2> = GEEPPF(<y1>,GAMMA)             <SUBSET/EXCEPT/FOR qualification>
    where <y1> is a variable, number, or parameter;
                <y2> is a variable or a parameter (depending on what <y1> is) where the computed geometric extreme exponential ppf value is stored;
                <GAMMA> is a positive number or parameter that specifies the shape parameter;
    and where the <SUBSET/EXCEPT/FOR qualification> is optional.
Examples:
    LET A = GEEPPF(3,2)
    LET A = GEEPPF(A1,4)
    LET X2 = GEEPPF(X1,8)
Default:
    None
Synonyms:
    None
