Which of the following can NOT be used for stepwise regression analysis?

Stepwise regression is a statistical method that involves adding or removing predictors from a multivariate model based on their statistical significance. The tools that can be used for stepwise regression typically need to have data analysis functions and the ability to run statistical models.

Microsoft Excel is capable of performing stepwise regression through its add-ins or built-in data analysis toolpack. Lotus, though dated, can also handle statistical computations, and Microsoft Access is a database management tool but can execute SQL queries and small statistical analyses, making it a candidate for running regression analyses with proper setup.

On the other hand, Microsoft Word is primarily a word processing application. It does not have the capability to perform statistical analyses or regression modeling, which is why it cannot be used for stepwise regression. Understanding the specific functionalities and primary purposes of these applications clarifies why Microsoft Word stands out as the option that cannot facilitate stepwise regression analysis.
