Using matrix formulation and MS excel matrix function you may learn how to compute regression in matrix model. 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. Data analysis has advantage to compute the statistical criteria such as R square, ANOVA and t statistics plus probability plots of outlier. If your data change dynamically, the result of regression will change immediately. Using MS Excel Spreadsheet for manual computationĮxcel function is very handy. Using Microsoft Excel, you have at least five methods to compute linear regression You may download the spreadsheet example of this tutorial here You will also learn how to solve regression using generalized inverse matrix. 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. This tutorial is an introduction to regression model using MS Excel. Regression Analysis using Microsoft Excel
