Answer for screen readers
The term 'step 2' and 'r variable' might refer to stepwise regression methods in R or creating/managing variables in R. Stepwise regression is a statistical method for model selection, and R is a programming language used for statistical analysis.
More Information
Stepwise regression involves adding or removing predictors based on statistical significance. In R, variables can be easily created or modified using different operators and functions, making it useful for data analysis and modeling.
