Interpreting the logistic regression model
- [Instructor] So now we are back to thinking about our final model. I have opened your exercise file named 610_Stepwise Selection Logistic-Round 2. I wanted to point out our final model, which is model 75. Let's go look at it for a moment. See how the last line of the model statement has the covariates that were added during round two? You can tell. Age six is first, and we know we tried the age covariates early in round one and they were kicked out. So with age six on the last line, we know it managed to make it back into the model during round two, which is fine for age six, but the problem for us is that model 75, as it is written here, has the covariates out of order compared to our table one. So when I'm done with round two modeling, I like to make a separate code file where I copy in the final model and tidy it up a bit. In fact, I put that code file in your exercise files. It's called 615_Final Logistic Model. Let's open it and look at it. Okay, here we are in 615_Final…
