How can I conduct a discriminant analysis with a model that does not have a constant term using a command syntax of the "Discriminant" procedure?

  • 1.  How can I conduct a discriminant analysis with a model that does not have a constant term using a command syntax of the "Discriminant" procedure?

    Description: The discriminant procedure assumes a discriminant model having a constant term. Namely, it uses the discriminant function:

    f = a0 + a1*x1 + a2*x2 + ...

    where f is a category label, a_i is a coefficient, and x_i is an independent variable. I want to know the syntax for discriminant analysis without having the constant term. Namey, the discriminant function is

    f = a1*x1 + a2*x2 + ... .

    I cannot find an option to remove the constant term (a0) in the Discriminant procedure. (If the Discriminant procedure cannot do this analysis, can some other procedures do it?)
