NORHAZ

Name:
    NORHAZ (LET)
Type:
    Library Function
Purpose:
    Compute the normal (i.e, mean=0, sd=1) hazard function.
Description:
    The normal distribution has the following hazard function:

      h(x)=NORPDF(x)/(1 - NORCDF(x))   -infinity <= x <= infinity

    where NORPDF is the normal probability density function and NORCDF is the normal cumulative distribution function.

Syntax:
    LET <y2> = NORHAZ(<y1>,<loc>,<scale>)             <SUBSET/EXCEPT/FOR qualification>
    where <y1> is a number, parameter, or variable;
                <y2> is a parameter or variable (depending on what <y1> is) where the computed normal hazard value is stored;
                <loc> is a number, parameter, or variable containing the location parameter;
                <scale> is a number, parameter, or variable containing the scale parameter;
    and where the <SUBSET/EXCEPT/FOR qualification> is optional.

    The location and scale parameters are optional.

Examples:
    LET A = NORHAZ(3)
    LET A = NORHAZ(A1)
    LET X2 = NORHAZ(X1,10,50)
Default:
    None
Synonyms:
