UPCOMING WEBINAR: The Roadmap for Market Researchers in the Age of AI This article describes how to test for heteroscedasticity (non-constant variance) in the residuals of linear regression models. Also known as the Breusch-Pagan test. The null hypothesis of the test is homoscedasticity.
Requirements
- A Linear Regression model output.
Method
- Select the linear regression output.
- Go to the object inspector
> Data > Diagnostics >Test Residual Heteroscedasticity.
