Question 21

What is meant by "informative missingness" in the context of linear regression?

A.Missing data that leads to multicollinearity among predictors

B.Missing data that is unrelated to the outcome variable

C.Missing data that is randomly distributed across observations

D.Missing data that provides valuable information about the outcome

Question 22

You want to fit a Poisson regression and use the log link function to predict skin cancer from weather, pollution, and demographic variables. Each row in the data is a geographic region.
The response, Melanoma, is stored as the number of melanoma skin cancer cases in each region.
Because some regions have many people and some have few, your data also includes a variable with the region population.
What is the best way to include population in this model?

A.Add the log of Population as an effect.

B.Add Population as an effect.

C.Add Population as an offset.

D.Add the log of Population as an offset.

Question 23

When assessing the quality of a linear regression model, what does a low p-value associated with the F-statistic suggest?

A.The model has a weak linear relationship with the response.

B.The model is a poor fit for the data.

C.The model has a significant overall explanatory power.

D.The model has a high level of multicollinearity.

Question 24

Which statement is true about performing regressions in SAS Visual Statistics?

A.You can specify a multinomial classifier as the response variable with linear regression.

B.You can specify an ordinal classifier as the response variable with linear regression.

C.You can build neither a linear regression nor a logistic regression with a generalized linear model.

D.You can build both a linear regression or a logistic regression with a generalized linear model.

Question 25

How does SAS Data Integration Studio facilitate scoring new data using exported score code?

A.By enabling the scheduling of batch scoring jobs

B.By generating score code automatically during ETL processes

C.By providing a visual interface for connecting to external data sources

D.By automatically tuning hyperparameters for scoring
