Multiple Regression Analysis using Stata Introduction. Multiple regression (an extension of simple linear regression) is used to predict the value of a dependent variable (also known as an outcome variable) based on the value of two or more independent variables (also known as predictor variables). Simple linear regression is a method you can use to understand the relationship between an explanatory variable, x, and a response variable, y. This tutorial explains how to perform simple linear regression in Stata. Example: Simple Linear Regression in Stata familiar with regression in Stata.
Then iteration process begins in which weights are calculated based on absolute residuals.

You can get these values at any point after you run a regress command, but remember that once you run a new regression, the predicted values will be based on the most recent regression.
