ANSWER:Step 1 of 7
Regression is a statistical method that is used to model the relationship between two or more variables. It is a powerful tool that can be used to make predictions, identify patterns, and test hypotheses. Regression models are typically classified into two types: linear and nonlinear. Linear regression models assume that the relationship between the dependent variable and the independent variables is linear. Nonlinear regression models, on the other hand, allow for more complex relationships between the variables.
