SLAPDF
Name:
Type:
Purpose:
Compute the slash probability density function.
Description:
The slash distribution has the following probability density
function:
with
denoting the probability density function of the standard
normal distribution.
The most common use of the slash distribution is in
simulation studies. It is a useful distribution in this
context because it has heavier tails than a normal distribution,
but it is not as pathological as the Cauchy distribution.
Syntax:
LET <y> = SLAPDF(<x>)
<SUBSET/EXCEPT/FOR qualification>
where <x> is a variable, a number, or a parameter;
<y> is a variable or a parameter (depending on what
<x> is) where the computed slash pdf value is
stored;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.
Examples:
LET A = SLAPDF(3)
LET X2 = SLAPDF(X1)
Note:
You can generate random numbers from a slash distribution
with the following command:
LET Y = SLASH RANDOM NUMBERS FOR I = 1 1 N
