| Functions and CALL Routines |
Returns the softmax value.
|
CALL SOFTMAX(argument<,argument,...>);
|
-
argument
-
is numeric.
| Restriction: |
The CALL SOFTMAX routine only accepts
variables as valid arguments. Do not use a constant or a SAS expression because
the CALL routine is unable to update these arguments. |
The CALL SOFTMAX routine replaces each argument with the
softmax value of that argument. For example
![[equation]](images/leqn24.gif)
is replaced by
![[equation]](images/deqn26.gif)
If any argument contains a missing value, then CALL SOFTMAX
returns missing values for all the arguments. Upon a successful return, the
sum of all the values is equal to 1.
The following SAS statements produce these
results:
