Its curve-fitting capabilities make it an excellent tool to perform nonlinear regression. The Excel Solver will find the equation of the linear or nonlinear curve which most closely fits a set of data points. This dataset is also used in the two tutorials on simple linear regression and ANCOVA. Setting up a multiple linear regression. After opening XLSTAT, select the XLSTAT / Modeling data / Regression function.

All VIF is less than 3, so there is no multicolinearity. Multiple Regression Analysis in Excel Regression analysis describes the relationships between a set of independent variables and the dependent variable. It produces an equation where the coefficients represent the relationship between each independent variable and the dependent variable. You can also use the equation to make predictions.
Excel Multiple Regression DEFINITION: Multiple regression is a method used in statistics to predict the outcome of a response or dependent variable using two or more explanatory or independent variables. In this tutorial, we will show how to do multiple regression using Excel. Multiple Linear Regression in Excel You saw in the pressure drop example that LINEST can be used to find the best fit between a single array of y-values and multiple arrays of x-values. In that example, we raised the x-values to the first and second power, essentially creating two arrays of x-values. Similarly, we can calculate the power for Example 1 of Multiple Regression using Excel to be 99.9977% and the power for Example 2 of Multiple Regression using Excel to be 98.9361%. Example 2: What is the size of the sample required to achieve 90% power for a multiple regression on 8 independent variables where R 2 = .2, α = .05? The Standard Error of the Regression is found to be 21,502,161 in the Excel regression output as follows: (Click On Image To See a Larger Version) Prediction Interval est = 49,143,690 ± TINV (0.05, 18) * (21,502,161)* 1.1 Prediction Interval est = [49,143,690 ± 49,691,800 ]
Delete a variable with a high P-value (greater than 0.05) and rerun the regression until Significance F drops below 0.05.
