IWEPPF
Name:
Type:
Purpose:
Compute the standard form of the inverted Weibull percent
point function with tail length parameter
.
Description:
The standard form of the inverted Weibull percent point
function is:
Syntax:
LET <y> = IWEPPF(<p>,<GAMMA>)
<SUBSET/EXCEPT/FOR qualification>
where <p> is a variable, number, or parameter;
<y> is a variable or a parameter (depending on what
<p> is) where the computed inverted Weibull ppf
value is stored;
<GAMMA> is a positive number or parameter that
specifies the tail length parameter;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.
Examples:
LET A = IWEPPF(0.9,2)
LET A = IWEPPF(A1,4)
LET X2 = IWEPPF(P,8)
