In Stata use the command regress, type: Regression analysis is about exploring linear relationships between a dependent variable and one or more independent variables. Most Stata commands and user-written programs can be used with bootstrap, as long as they follow standard Stata syntax; see [U] 11 Lan-guage syntax. To explore this relationship, we can perform simple linear regression using weight as an explanatory variable and miles per gallon as a response variable. When reading this manual, you will find references to other Stata manuals.
