    Exclamation Question about logistics regression.



    I have question about logistics regression.
    I have 3 year survey data 2005,2006,2007. Risk behavior, let say r1 r2 r3 r4 …etc and outcome (which is categorical data: outcome1 outcome2 outcome3).
    I coded year as 1,2,3.
    I want to have a polytomous logistic regressiob model and use year as a weight

    I use the formula as follows:
    proc logistic data=one;
    class outcome (ref=' outcome1)/ param=ref ref=first order=internal;
    model outcome= r1 r2 r3 r4.../ nodummyprint;
    weight year;
    run;

    was this right?
    I am confuse. Can somebody help me, please??

    Thank you

    Re: Question about logistics regression.

    try tying in "link=glogit" after "nodummyprint"

    If that still doesn't work, look into this document:
