Linear regression is the most basic and commonly used predictive analysis. Regression estimates are used to describe data and to explain the relationship between one dependent variable and one or more independent variables.
Multiple regression applies when the researcher compares 2 or more continuous independent variables against 1 continuous dependent variable. The number of levels of a categorical variable can also drive which statistical test to use.
