MULTIPLE LINEAR REGRESSION ANALYSIS USING MICROSOFT EXCEL by Michael L. Orlov Chemistry Department, Oregon State University (1996) INTRODUCTION In modern science, regression analysis is a necessary part of virtually almost any data reduction process. Popular spreadsheet programs, such as Quattro Pro, ...
This tutorial will help you set up and interpret a multiple linear regression in Excel using the XLSTAT software. Linear regression is based on Ordinary Least Squares (OLS). Not sure this is the modeling feature you are looking for? Check out this guide. Dataset for running a multiple linear...
While we are certainly interested in the very best regression model, it is a very wise to view the best, say, 50 models. The reason is that if the user has several sets of similar data (each having its own errors) then a possible best empirical regression model will consistently appear ...

The multiple linear regression estimates are computed by the StatCalc plug-in in Excel, as shown in table 2.2. Table 2.2 The equation for predicting efficiency is Y=13.182+0.5830.044+0.3290.057+0.1120.197 1X2X3X4X5X6X In Table 2.3, we use ten examples as validation data. Apply the pre...
Multiple linear regression (MLR) is a statistical technique that uses several explanatory variables to predict the outcome of a response variable.
We can also build the linear model using the LINEST function (array formula) in Excel. The syntax of the LINEST function is =LINEST(known y’s, known x’s, constant, stats) where the constant can be 0 or FALSE (for a model with no intercept), or 1 or TRUE (for a model with int...

Using the full correlation matrix can facilitate the implementation of Excel function in removing the multicollinearity source variables. It is found that this procedure is easier and time-saving especially when dealing with greater number of independent variables in a model and a large number of all...
