DIWPPFName:
with q and denoting the shape parameters.
<SUBSET/EXCEPT/FOR qualification> where <p> is a positive integer variable, number, or parameter in the interval (0,1); <q> is a number, parameter, or variable in the range (0,1) that specifies the first shape parameter; <beta> is a number, parameter, or variable that specifies the second shape parameter; <y> is a variable or a parameter (depending on what <x> is) where the computed discrete Weibull ppf value is stored; and where the <SUBSET/EXCEPT/FOR qualification> is optional.
LET Y = DIWPPF(P,0.3,0.7) PLOT DIWPPF(P,0.6,0.4) FOR P = 0 0.01 0.99
