Residual Plots – will create a scatter graph where the residuals are plotted on the Y axis and the X variable is plotted on the X axis.Standardized Residuals – will return the standardized residuals these values can be useful when identifying potential outliers.Residuals – will return the list of predicted dependent values, based on the regression line, as well as the residual values for each point.The final set of options concerns the residuals in the analysis.

New Workbook – lets you save the results in an entirely separate workbookįor my example, I’m going to select the second option and have the results placed in a new worksheet.New Worksheet Ply – lets you place the results in a new worksheet.Output Range – you can highlight where you want the results to be placed in that worksheet.Output optionsįor the Output Options, you can specify where you want the regression results to be placed. However, if you want to use a different confidence level than 95%, then you need to select this option and enter the desired value here. By default, the results will return the 95% confidence intervals without having to change any options. It is also possible to specify the confidence level for the test. Generally, for linear regression, this option is not selected, so I will leave it unchecked for this example. Doing so would mean there is no Y intercept in the model. The next option called Constant is Zero is used if you want the regression line to start at 0, otherwise known as the origin. If you didn’t have any labels when you selected your data, then you should not tick this option. If you have highlighted the labels of the columns when selecting the data, then tick the Labels options. Input X Range – this is the data for the X variable, otherwise known as the independent variable.The Y variable is the one that you want to predict in the regression model. Input Y Range – this is the data for the Y variable, otherwise known as the dependent variable.To perform the linear regression, click on the Data Analysis button. Performing the linear regression in Excel The coefficients table shows that value and capital have a significant positive effect on Gross investment.We are now ready to perform the linear regression in Excel. The p-value associated to the F statistic shows that the model is significantly different from a null model. Interpretation of an Panel regression output For fixed effects, you should select a Within model.Ĭlick OK to launch computations. Select a Random model to consider time and panel units effect as random. This will build a model that controls both for time and panel units. In the Options tab, choose the two-ways effect. Select the Year data under the Time field and Firm data under the Individuals field. Select the value & capital data under the Quantitative Explanatory Variables field.

In the general tab, select the inv column under the dependent variables field. Open XLSTAT-R / plm / Panel regression(plm) Setting up a Panel regression in XLSTAT-R The goal here is to model gross investment according to value and capital, while controlling for Firm (panel units) and year (time). The data contains 5 columns corresponding to: (2010) “The Grunfeld Data at 50”, German Economic Review, 11(4), pp. thesis, Department of Economics, University of Chicago. Grunfeld, Yehuda (1958) The Determinants of Corporate Investment, Ph.D. (2013) Econometric Analysis of Panel Data, 5th ed., John Wiley and Sons (2001) Econometric Analysis of Panel Data, 2nd ed., John Wiley and Sons īaltagi, Badi H. The data correspond to Grunfeld’s investment data. Data set for launching a Panel Regression analysis in XLSTAT-R The panel regression function developed in XLSTAT-R calls the plm function from the plm package in R (Yves Croissant). Panel regression allows controlling both for panel unit effect and for time effect when estimating regression coefficients. Those units can be firms, countries, states, etc. It is widely used in econometrics, where the behavior of statistical units (i.e. Panel regression is a modeling method adapted to panel data, also called longitudinal data or cross-sectional data.
