It keeps going as we add more independent variables until we finally add the last independent variable, x_n, to the equation. For example, x_1 is the value of the first independent variable, x_2 is the value of the second independent variable, and so on. In this equation, the subscripts denote the different independent variables. To account for this change, the equation for multiple regression looks like this: The difference between the equation for linear regression and the equation for multiple regression is that the equation for multiple regression must be able to handle several inputs, instead of only the single input of linear regression.
Here, y is the dependent variable, x is the independent variable, and A and B are coefficients dictating the equation. To start, let’s look at the general form of the equation for linear regression : Multiple regression is specifically designed to create regressions on models with a single dependent variable and multiple independent variables.īack to Basics What Is Linear Regression?

1.9 presents how to obtain the regression coefficients by SPSS.īorgatta EF, Bohrnstedt GW (1980) Levels of measurement, once over again. Section 1.8 discusses what are the assumptions of the multiple linear regression and how can deal with the multicollinearity and unusual cases. Section 1.7 shows how a qualitative variable can be used as a binary or dummy variable in the linear regression. Section 1.6 emphasizes that the appropriate regression method for testing hypotheses is enter method.
Section 1.5 presents how the effects of the variables can be controlled. Section 1.4 presents how the assumed causal relationships are confirmed and what is the total contribution of the variables to the variation of the dependent variable. Sections 1.2 and 1.3 give a brief overview of the changes of the regression coefficients by the entering or removing the correlated or uncorrelated variables. It illustrates how the dependent variable (effect) is related to each of the independent variables (causes) as regression coefficients. Section 1.1 shows how this technique can recreate the real relationships between the variables (phenomena) as a regression equation. This chapter describes the multiple linear regression by a nontechnical language and simple examples.
