Hi I'm new here and I could really use some help:
I have a dataset of N=50 patients and 20 variables. 13 are categorical and 7 are continuous variables. I have no missing values. My outcome is one of the variables and it is a binary outcome, 1= yes disease, 0= no disease.
I want to run an analysis for multivariate predictors of disease. Using logistic regression and doing a backwards stepwise multivariate analysis.
I used the commands:
sw logistic var1 var2 var3 var4 var5, pr(0.5)
where var1=the outcome variable (binary)
var2= categorical (1,2,3,4,5)
var3= continuous
var4= categorical
and so forth.
I am not sure how to interpret the Odds Ratio and don't quite understand what I am getting.
Can someone please explain to me how to run a backward stepwise multivariate analysis on my specific dataset.
thank you!
