Expert Solution
Step 1
A regression model provides a function that describes the relationship between one or more independent variables and response, dependent, or target variable.
Regression analysis is the basis for many types of prediction and for determining the effects on target variables. A linear regression line has an equation of the form Y=a+bX.
