I have run an ordinal logistic regression in R (see script below) and it runs fine. Now I have decided I want to control for a few demographics such as age, gender. However, I am not sure how to add these variables into the script in a way which will cause the regression to control for them. Anyone know how to do this?
glmIdentity <- polr(as.factor(SupportCI) ~ IT + CIdentity + DIdentity + Q86_3 + Q87_3, data = df, Hess = TRUE)
