Method 1 – Perform Regression Analysis in Excel Using LINEST Function. The syntax of the LINEST function is as follows: =LINEST(known_y’s, [known_x’s], [const], [stats]) We’ll use the following dataset to perform regression analysis using the LINEST function.
You can use the LINEST function to quickly find a regression equation in Excel. This function uses the following basic syntax: LINEST(known_y's, known_x's) where: known_y’s: A column of values for the response variable. known_x’s: One or more columns of values for the predictor variables.

Linear regression equation. Simple linear regression draws the relationship between a dependent and an independent variable. 👉 The dependent variable is the variable that needs to be predicted (or whose value is to be found). 👉 The independent variable explains (or causes) the change in the dependent variable.
