WebMar 26, 2016 · The growth rate can be estimated, but a log transformation must be used to estimate using OLS. If you begin with an exponential growth model and take the log of both sides, you end up with ln Y = ln Y 0 + Xln (1 + r), where ln Y 0 is the unknown constant and ln (1 + r) is the unknown growth rate plus 1 (in natural log form). You end up with the ... WebApr 25, 2024 · Step 2: Fit the Exponential Regression Model. Next, we fill fit the exponential regression model. Press Stat, then scroll over to CALC.
