Syntax

CALL LOGISTIC(argument<, argument, ...>)


Arguments

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.

Details

The CALL LOGISTIC routine replaces each argument by the logistic value of that argument. For example [equation] is replaced by

[equation]

If any argument contains a missing value, then CALL LOGISTIC returns missing values for all the arguments.

Examples

The following SAS statements produce these results.

SAS Statements Results
x=0.5;
y=-0.5;
call logistic(x,y);
put x= y=;
 

x=0.6224593312 y=0.3775406688
