Which of the following is a primary assumption in linear regression analysis?

Answer: The relationship between the variables is linear

Linear regression assumes that the relationship between the dependent and independent variables is linear, among other conditions.

What does the PRESS statistic in PROC REG measure?

Answer: The sum of the squared leave-one-out prediction residuals

PRESS sums the squared residuals from predicting each observation with a model fit without it; lower values indicate better predictive ability.

Which of the following is a commonly used method for handling missing data in statistical analysis?

Answer: Imputation

There are several methods to handle missing data, including imputation and deletion methods.

Which PROC LOGISTIC MODEL statement option requests the generalized (Cox-Snell) and max-rescaled R-square?

Answer: RSQUARE

The RSQUARE option prints the generalized R-square and the max-rescaled R-square.

What does the 'INFILE' statement do in SAS?

Answer: It identifies the external file to read data from.

The 'INFILE' statement is used to specify the file to read in a 'DATA' step.

What does ODS stand for in SAS?

In PROC TABULATE, which keyword in the TABLE statement creates an 'All' category row or column that includes totals across all levels of a classification variable?

Answer: ALL

The ALL keyword in PROC TABULATE's TABLE statement generates an additional category that includes all observations, effectively displaying a total across the variable's levels.

A plot of residuals against predicted values fans out as the predicted values increase. Which assumption is violated?

Answer: Constant variance (homoscedasticity)

A funnel shape means the error variance changes with the fitted value.

Which of the following is an example of a validation technique in software development?

Answer: User acceptance testing (UAT)

Validation techniques ensure that the software works as intended from the end-user's perspective.

A confusion matrix shows TP=80, FN=20, FP=30, TN=870. What is the misclassification rate?

Answer: 5.0%

Misclassification = (FN + FP) / Total = 50/1000 = 5%.

An analyst completes a SAS e-learning course. What do they usually receive?

Answer: A course completion record or badge, separate from certification

Course completion is recognized separately; certification still requires passing the exam.
