The LINEST function uses the least squares regression method to calculate a straight line that best explains the relationship between your variables and returns an array describing that line. Multiple linear regression is a method we can use to understand the relationship between two or more explanatory variables and a response variable. This tutorial explains how to perform multiple linear regression in Excel. Note: If you only have one explanatory variable, you should instead perform simple linear regression. Example: Simple Linear Regression in Excel Suppose we are interested in understanding the relationship between the number of hours a student studies for an exam and the exam score they receive. To explore this relationship, we can perform simple linear regression using hours studied as an explanatory variable and exam score as a response variable.
