This tutorial is an introduction to regression model using MS Excel. You will learn how to model you data, find the best-fit model and use graph, functions and Add Ins wizard in MS excel to automate the regression. You will also learn how to solve regression using generalized inverse matrix. You may download the spreadsheet example of this tutorial here.
Using Microsoft Excel, you have at least five methods to compute linear regression
Using Excel function
Using Data Analysis Add Ins
Using MS Excel Graph trend Analysis
Using MS Excel matrix function
Using MS Excel Spreadsheet for manual computation
Excel function is very handy. If your data change dynamically, the result of regression will change immediately. Data analysis has advantage to compute the statistical criteria such as R square, ANOVA and t statistics plus probability plots of outlier. Excel Graph trend analysis is very good for plotting the graph of linear and several non-linear models (exponential, logarithm, power and polynomial), the update is also dynamic according to your data change.
Using matrix formulation and MS excel matrix function you may learn how to compute regression in matrix model. Together with using spreadsheet for manual computation, both methods have educational advantage to explain the formula of regression.
