Given that each of the VIF values for the explanatory variables in our regression model are close to 1, multicollinearity is not a problem in our example.Install the Excel Data Analysis Tool Pack

In this case, the coefficient estimates and p-values in the regression output are likely unreliable.

A value greater than 5 indicates potentially severe correlation between a given explanatory variable and other explanatory variables in the model.

A value between 1 and 5 indicates moderate correlation between a given explanatory variable and other explanatory variables in the model, but this is often not severe enough to require attention.

A value of 1 indicates there is no correlation between a given explanatory variable and any other explanatory variables in the model.

A general rule of thumb for interpreting VIFs is as follows: The value for VIF starts at 1 and has no upper limit.

Rebounds: 1.18 How to Interpret VIF Values It turns out that the VIF for the three explanatory variables are as follows: We can then repeat this process for the other two variables assists and rebounds. The VIF for points is calculated as 1 / (1 – R Square) = 1 / (1 –. Next, we can calculate the VIF for each of the three explanatory variables by performing individual regressions using one explanatory variable as the response variable and the other two as the explanatory variables.įor example, we can calculate the VIF for the variable points by performing a multiple linear regression using points as the response variable and assists and rebounds as the explanatory variables. Step 2: Calculate the VIF for each explanatory variable.

Select Regression and click OK.įill in the necessary arrays for the response variables and the explanatory variables, then click OK. Once you click on Data Analysis, a new window will pop up.

Step 1: Perform a multiple linear regression.Īlong the top ribbon, go to the Data tab and click on Data Analysis. If you don’t see this option, then you need to first install the free Analysis ToolPak. Then, we’ll identify the VIF values for each explanatory variable. We will fit a regression model using rating as the response variable and points, assists, and rebounds as the explanatory variables.

Example: Calculating VIF in Excelįor this example we will perform a multiple linear regression using the following dataset that describes the attributes of 10 basketball players.

This tutorial explains how to calculate VIF in Excel. If the degree of correlation is high enough between variables, it can cause problems when fitting and interpreting the regression model.įortunately, it’s possible to detect multicollinearity using a metric known as the variance inflation factor (VIF), which measures the correlation and strength of correlation between the explanatory variables in a regression model. Multicollinearity in regression analysis occurs when two or more explanatory variables are highly correlated to each other, such that they do not provide unique or independent information in the regression model.
