Create a calculated item that divides total amount of sales by the total amount of items sold. C. Create an aggregated measure using the Avg aggregation on total amount of sales. D. Create a calculated item by duplicating the original model effect and changing its default aggregation to Average.

Correct Answer: D

Question 6

How can you assign a group-by variable to a predictive model in SAS Visual Analytics?

Correct Answer: A,C

Question 7

In a generalized linear model, what is the role of the link function in transforming the linear predictor?

Correct Answer: C

Question 8

What is the primary purpose of reviewing the residual plot in linear regression analysis?

A. To calculate the coefficient of determination (R-squared) B. To determine the p-value associated with the response variable C. To assess the linearity assumption and identify potential issues D. To detect outliers in the predictor variables
