In Excel, the LINEST function is used to do linear regression. Y=m 1x 1+ m 2x 2+…+m nx n+b LINEST Function The equation for multiple linear regression is: In this equation, m is called “slope” and b is called “intercept.” The equation for the simple linear equation is: If we have one independent variable, the regression is called simple linear regression, but when we have more than one independent variable, it is called multiple linear regression. The use of linear regression is to estimate the value of the dependent variable using the independent variable and the regression equation. Introduction to Linear RegressionĪs mentioned above, in linear regression, we have an independent variable and a dependent variable, so we seek to examine the relationship between the dependent and independent variables. In this blog, we are going to introduce the LINEST function and discuss how it works. Among Excel statistical functions, the LINEST function is used for linear regression calculations. In statistical modeling, regression means studying the relationship between a variable (dependent variable) and one or more variables (independent variable).
