The first assumption of linear regression is that there is a linear relationship between the independent variable, x, and the independent variable, y. How to determine if this assumption is met. The easiest way to detect if this assumption is met is to create a scatter plot of x vs. y. Assumptions of Linear Regression Linear relationship One of the most important assumptions is that a linear relationship is said to exist between the dependent and the independent variables. Using SPSS to examine Regression assumptions: Click on analyze >> Regression >> Linear Regression Then click on Plot and then select Histogram, and select DEPENDENT in the y axis and select ZRESID in the x axis. The first assumption of linear regression talks about being ina linear relationship.

The model’s performance will be very good if these assumptions are met. In the picture above both linearity and equal variance assumptions are violated. There is a curve in there that’s why linearity is not met, and secondly the residuals fan out in a triangular fashion showing that equal variance is not met as well. Using SPSS to examine Regression assumptions: Click on analyze >> Regression >> Linear Regression Linear regression (Chapter @ref(linear-regression)) makes several assumptions about the data at hand.

As you probably know, a linear regression is the simplest non-trivial relationship. It is called linear, because the equation is linear. Each independent variable is multiplied by a coefficient and summed up to predict the value of the dependent variable. Linear regression is fairly robust for validity against nonnormality, but it may not be the most powerful test available for a given nonnormal distribution, although it is the most powerful test available when its test assumptions are met.
