logistic regression using multiple categories

[stellapersis7]

Hi all,

So I am doing a class project.

My outcome variable is SDM and has 3 categories - poor, average and optimal.

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. 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.

Thanks

Is your question about how to do 2-level model or to combine the results of different 2-level models into a single output table?
