In summary, have 3 output types and we'll cover them one by one: Now comes the complicated aspect of our analysis: interpret the results of the predictive model in Excel. Implementing the linear regression model was the easy part. Analyzing the results of our predictive model in Excel Press OK And finally we have performed a regression analysis in Excel in just two steps!! Wasn't it so easy? Now we will see the result of the regression analysis in Excel. The other options are discretionary and you can select them for your specific purpose.

Output range: the range of cells where you want to display the results.

Input range x: the range of dependent factors.

Input range and: the range of the independent factor.

In this step, we will select some of the necessary options for our analysis, such as: Go to Data Analysis in the Data Toolkit, select Regression and press OK: The company wants to predict sales through each customer considering the following factors: customer revenue, distance from house to store, client operating frequency per week. There is a shoe sales company in the town of Winden. Here is the statement of the problem that we will work with:

Now, let's dive into Excel and run linear regression analysis! Let's start building our predictive model in Excel!! Implementation of linear regression in Excel You have successfully added the Analysis Toolkit in Excel!! You can check it by going to Data bar on tape. Select the “ Analysis Toolkit“And press OK: Go to Accessories in the left panel -> Manage Excel add-ins -> Ir: To add it to your workbook, follow these steps. Analysis ToolPak in Excel is a companion program that provides data analysis tools for statistical and engineering analysis.

To perform a regression analysis in Excel, first we need to enable Excel Analysis Tools Plugin. Your goal is to reduce the sum of squares to produce the line of best fit like this:įor more information on linear regression, here are some resources: Get the Excel Add-in for the All-Important Analysis ToolPack The most common method to perform regression is the OLS (ordinary least squares). The coefficients are basically the weights assigned to the characteristics, depending on its importance. Here, we have Y as our dependent variable, the X's are the independent variables and all the C's are the coefficients. Linear regression gives us an equation like this: It is a linear approach to statistically model the relationship between the dependent variable (the variable you want to predict) and the independent variables (the factors used to predict). It is also the most widely used supervised learning technique in the industry. Linear regression is the first machine learning technique most of us learn.

Interpretation of the results of our predictive model.

In this article, i am going to explain how to build a linear regression model in excel and how to analyze the result so that you can become a superstar analyst. And we don't need to be a master of Excel or Statistics to do predictive modeling!! We can easily build a simple model like linear regression in MS Excel which can help us to perform analysis in few simple steps.

Microsoft Excel offers us the ability to create predictive models without having to write complex code that flies over most people's heads. And learning analytics or hiring an analyst might be beyond your reach. Now you must be wondering how the heck they will build a complex statistical model that can predict these things.
