| Functions and CALL Routines |
Applies the logistic function to each argument.
|
CALL LOGISTIC(argument<, argument,
...>)
|
-
argument
-
is a numeric variable.
| Restriction |
The CALL LOGISTIC
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 LOGISTIC routine replaces each
argument by the logistic value of that argument. For example
![[equation]](images/leqn15.gif)
is replaced by
![[equation]](images/deqn22.gif)
If any argument contains a missing value, then CALL LOGISTIC
returns missing values for all the arguments.
The following SAS statements produce these
results.
