You want to use a generalized linear model to predict donation amount from a set of demographics predictors. Donation amount is known to be right-skewed, with many non-donors (donation amount = 0).
Which settings in the Generalized Linear Model task are most appropriate for modeling this response?

• A. 
• B. 
• C. 
• D. 

Given an Influence Plot generated in a Linear Regression within SAS Visual Statistics, which diagnostic can be used to quantify leverage?

• A.  Concordance
• B.  Likelihood Displacement
• C.  AIC
• D.  Adjusted R-Squared

What does adding an interaction effect in linear regression modeling allow you to capture?

• A.  The joint impact of two or more predictors on the response variable
• B.  The effect of missing data on the model
• C.  The presence of outliers in the data
• D.  The multicollinearity among predictors

How can predicted values be derived and described in terms of predicted probabilities in SAS Visual Statistics?

• A.  By calculating the mean of the predictor variables
• B.  By fitting a linear regression model to the data
• C.  By summing the residuals of the model
• D.  By applying the link function to the linear predictor

When interpreting a Residual Plot, what does it reveal about the model's performance?

• A.  The p-values associated with the predictor variables
• B.  The linear relationship between predictors and the response
• C.  The presence of any outliers or patterns in prediction errors
• D.  The distribution of predictor variables in the dataset
