Multiple linear regression MLR , also known simply as multiple regression, is a statistical technique that uses several explanatory variables to predict the outcome of a response variable. The goal of multiple linear regression MLR is to model the linear relationship between the explanatory independent variables and response dependent variable. In essence, multiple regression is the extension of ordinary least-squares OLS regression because it involves more than one explanatory variable. Simple linear regression is a function that allows an analyst or statistician to make predictions about one variable based on the information that is known about another variable. Linear regression can only be used when one has two continuous variables—an independent variable and a dependent variable. The independent variable is the parameter that is used to calculate the dependent variable or outcome.

Published on February 20, by Rebecca Bevans. Revised on October 26, Regression models are used to describe relationships between variables by fitting a line to the observed data.
Data analysis using multiple regression analysis is a fairly common tool used in statistics. Many graduate students find this too complicated to understand. However, this is not that difficult to do, especially with computers as everyday household items nowadays.
