In linear regression, what does the coefficient of determination (R-squared) measure?

• A.The p-value associated with the intercept term
• B.The goodness of fit of the model to the data
• C.The impact of outliers on the model
• D.The degree of multicollinearity among predictors

In linear regression, what does a high p-value for a predictor variable suggest?

• A.The predictor is a categorical variable.
• B.The predictor is not relevant for the model.
• C.The predictor is highly significant for the model.
• D.The predictor has a strong linear relationship with the response.

In linear regression modeling, what roles are typically assigned to variables?

• B.Intercept, Slope, and Error
• C.Dependent, Independent, and Categorical
• D.Predictor, Response, and Interaction

What is variable selection in SAS Visual Statistics used for in logistic regression modeling?

• A.To identify and choose relevant predictor variables

• D.To assign roles to variables

When would you typically use a linear regression model instead of a generalized linear model (GLM)?
