Risk adjustment basics
You're doing a story about a doctor with a high mortality rate. Is she a bad doctor or does she take the sickest patients? Or you're doing a story about a school with low test scores. Is it a bad school or does it have the hardest to teach students? How can you tell? The answer is risk adjustment. We'll show you how to use logistic regression and risk indices to make sure you're comparing apples to apples. Even if you never run a risk adjustment yourself, you'll learn how academics and government agencies risk adjust the data they release.
This session will be most useful if: You have a basic knowledge of statistics including the basics of regression.
