Odds ratio results

Chapi — Mon, 30 Nov 2020 10:27:56 GMT

Hello,

I am new to SAS, could you please help me how to generate exactly like in the below image results using proc logistic regression. I want to generate the odds ratio by categories in the variable and Confidence Intervals for the categories except the first category in the variables. I am trying to predict a binary outcome and need the odds ratio table exactly like below. Please can someone help me with it. Below is the sample dataset.

Target	Education	Health_insurance	Living_arrangement	Age	Sex
0	-0.08264447	-0.677142541	0.979974336	-0.607323603	-1.04615533

@Chapi can you provide the data you're working with or some of it?

Hello,
Thank you. Attached the sample dataset.

If that is all the data you have, it is pretty sparse as evidenced by running this:

proc freq; 
table (Education	Health_insurance	Living_arrangement	Age	Sex)*Target; 
run;

Note the occurrences of only a single count in one of the predictor levels. So, you can filter those out cases and get results for the remaining data:

proc logistic ;
where education<8.99941821  and Health_insurance<5.578245149 and
Living_arrangement<6.983458922 and	Age<3.014553778;
class Target	Education	Health_insurance	Living_arrangement	Age	Sex;
model Target(event="1")=	Education	Health_insurance	Living_arrangement	Age	Sex;
run;

It's odd and unnecessary to have obviously categorical variables be numerically coded like this - I think you did some sort of thins with WOE, but that isn't needed. The above gives the odds ratios you want. You can always save them into a data set using an ODS OUTPUT statement if you want to do some other work with them.
