Hi, Im running a logistic regression. And am confused as to which predictors are covariates and which are categorical covariates.
Q: A study aims to find predictors for cancer. The predictors are: Age (coded into 3 groups, 24-44, 45-64 and 65+), Alcohol consumption coded with 4 categories and Tobacco consumption coded with 4 categories?

Can i treat them all as categorical covariates?

Any help would be appreciated!
