![]() We see this by taking the exponential of both sides of the equation shown above and simplifying it to get Similarly, the log-log regression model is the multivariate counterpart to the power regression model examined in Power Regression. Namely, by taking the exponential of each side of the equation shown above we get the equivalent form Log-level regression is the multivariate counterpart to exponential regression examined in Exponential Regression. Keep in mind that the right side of these equations could also have a mix of log terms and non-log terms, such as y = b 0 + b 1 ln x 1 + b 2 x 2. Level-level regression is the normal multiple regression we have studied in Least Squares for Multiple Regression and Multiple Regression Analysis. We now briefly examine the multiple regression counterparts to these four types of log transformations: In Exponential Regression and Power Regression we reviewed four types of log transformation for regression models with one independent variable.
