Complete SAS Programming Guide - Learn SAS and Become a Data Ninja - Performing the Linear Regression

The video tutorial explains how to use a dataset related to Alzheimer's patients to perform regression analysis using SAS. It covers the setup of the regression model, including defining dependent and predictor variables, and explores various model options and calculations. The tutorial also demonstrates how to use plotting features in SAS, highlighting the potential to replace lengthy cognitive tests with a shorter screening process.

What is the primary purpose of using the seven-minute screen test in the context of Alzheimer's patients?

• To replace the need for a longer cognitive test

• To diagnose Alzheimer's disease

• To measure physical health

• To assess memory retention

In the regression setup process, which variable is considered the dependent variable?

• The seven-minute screen test

• The SAS procedure

• The imported dataset

• The cognitive battery test

What is the first step in setting up a regression analysis in SAS?

• Typing the model statement

• Importing the dataset

• Running the model

• Choosing the plot options

Which feature allows you to include additional calculations in the regression model?

• Changing the dataset

• Running the plot command

• Importing more data

• Using the slash (/) option

What is a limitation mentioned regarding the plotting feature in SAS?
