And you won't be surprised by the first thing you see here. See our first model, which we will name model three for documentation. It's exactly what we decided on, at the end of our last movie. It has the two covariates, Diab flag and Male in it. Let's run this model and see how it looks. This is exactly what we expected. Both covariates are significant. But what's important to us is that Male is significant. We would keep Diab flag no matter what, because it's our exposure. Now, before we make model four, we make a decision. We decide to retain Male in model four. Let's go back to our code, but then, what do we add to model four? If you look at our descriptive table for this hypothesis, you'll see the next row is Hispanic. So in model four, you will see I include the flag for Hispanic at the end, which I aptly named, Hispanic…
