Suppose you have a residuals plot that shows a funnel shape for the residuals. Which assumption of linear regression is being violated?
Question
Solution 1
The funnel shape in a residuals plot indicates a violation of the assumption of homoscedasticity in linear regression. Homoscedasticity assumes that the variance of the errors is constant across all levels of the independent variables. When this assumption is violated, it is known as heteroscedastic Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
