What should you do, for example, if you want lie calculate regresdion air quality changes when vehicle emissions decline? Or if you want to calculate how consumer purchasing behavior changes if a new tax policy is implemented?

To calculate these predicted effects, we can use a regression model. This module will first introduce correlation as an initial means of measuring the relationship between two variables. The module will then discuss prediction error linee a framework for evaluating the accuracy of estimates. Finally, the module will introduce the linear coefficiejt model, which is a powerful tool we can use to develop precise measures of how variables are related to each other.
