Hi
I’m asked to prepare a strategy such that the value of significant parameters (age,risk,pressure) estimate the odds that the person is a smoker
Risk Age Pressure Smoker
12 57 152 No
24 67 163 Yes
.....so on

How to estimate the odds ratio for the given parameters (Age,Risk,Pressure)?

PROC LOGISTIC can do this.

You would need to implement a logistic regression model to get the odds ratio. PROC LOGISTIC is a procedure that can be used to calculate the odds ratio.

Check the fully worked example here - click the link at the top of the page to get the code. Run it, make sure you understand it, then apply to your data. If you have categorical variables keep an eye on the CLASS statement and the design matrix to understand how its dummy coding the variables.
