Is It Interrupted Time Series or Just a Simple Dummy Variable?
This is a follow up from a previous paper that assumed three interrupted time series variable pairs. As I think about why the B-coefficients didn't make great sense, I wonder if they are just dummy variables. This paper explores that possibility. This topic is very important for students to understand as interrupted time series variables and dummy variables are powerful tools that they can apply to their future work.
