Use this tool to create a simple or multiple linear regression model for explanation or prediction. Available in Excel using the XLSTAT software.
Now go back to RegressIt and click the Linear Regression button on the ribbon to open the dialog box for specifying a regression model. Here GallonsPer100Miles has been selected as the dependent variable, and all other variables (except MPG) have been selected as independent variables. ...
Regression output can be interpreted for both the size and strength of a correlation among one or more variables on the dependent variable. Linear Regression in Finance The goal of a linear regression model is to estimate the magnitude of a relationship between variables and whether or not it is...
