For example, for the first model I need to consider only poor and average and for the second model i consider only poor and optimal.</P> <P>Thanks</P> Thu, 30 Nov 2023 21:21:49 GMT stellapersis7 2023-11-30T21:21:49Z https://communities.sas.com/t5/Statistical-Procedures/logistic-regression-using-multiple-categories/m-p/905442#M44935 <P>Hi all,</P> <P>So I am doing a class project.</P> <P>My outcome variable is SDM and has 3 categories - poor, average and optimal.</P> <P>I used multinomial regression but my professor also asked me to do it as 2 logistic regression models, like 1- poor vs average and 2- poor vs optimal and put it in a single table. how do I code for this.
