The regression analysis formula for the above example will be It can be manually enabled from the addins section of the files tab by clicking on manage addins, and then checking analysis toolpak. For further calculation procedure, refer to the given article here – Analysis ToolPak in Excel Analysis ToolPak In Excel Excel's data analysis toolpak can be used by users to perform data analysis and other important calculations. The regression analysis equation is the same as the equation for a line which is:įor the calculation of regression analysis, go to the “Data” tab in Excel and then select the “Data Analysis” option. In addition, it helps validate whether the predictor variables are good enough to help predict the dependent variable.Ī regression analysis formula tries to find the best fit line for the dependent variable with the help of the independent variables. One or multiple independent variables are chosen, which can help predict the dependent variable to predict the dependent variable. While running a regression analysis, the main purpose of the researcher is to find out the relationship between the dependent and independent variables. Regression is a statistical tool to predict the dependent variable with the help of one or more independent variables. Therefore, the formula for calculation is Y = a + bX + E, where Y is the dependent variable, X is the independent variable, a is the intercept, b is the slope, and E is the residual. Regression analysis is the relationship between dependent and independent variables as it depicts how dependent variables will change when one or more independent variables change due to factors.
