LOGHAZ

LOGHAZ (LET)

Library Function

Compute the logistic hazard function.

The standard form of the logistic distribution has the following hazard function:

LET <y> = LOGHAZ(<x>)             <SUBSET/EXCEPT/FOR qualification>
where <x> is a variable or a parameter;
            <y> is a variable or a parameter (depending on what <x> is) where the computed logistic hazard value is stored;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.

LET A = LOGHAZ(3)
LET X2 = LOGHAZ(X1)
