LDEPPF
Name:
Type:
Purpose:
Compute the standard form of the log double exponential (also
known as the log Laplace distribution) percent point
function.
Description:
Syntax:
LET <y> = LDEPPF(<p>,<alpha>)
<SUBSET/EXCEPT/FOR qualification>
where <p> is a variable, a number, or a parameter;
<y> is a variable or a parameter (depending on what
<p> is) where the computed log double exponential
ppf value is saved;
<alpha> is a variable, a number, or a parameter that
specifies the shape parameter;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.
Examples:
LET A = LDEPPF(0.9,2)
LET X2 = LDEPPF(P1,0.5)
