Quizplus · Accepted Answer

Collinearity diagnostics are used to determine the accuracy of a regression model by examining the level of correlation between predictor variables. High levels of collinearity can indicate that the model may be unstable or make it difficult to interpret the individual effects of each predictor variable. Therefore, collinearity diagnostics can help to improve the accuracy and reliability of the regression model. Choices A, B, and D are not accurate descriptions of the purpose of collinearity diagnostics.
