Exponential regression is probably one of the simplest nonlinear regression models. An example where an exponential regression is often utilized is when relating the concentration of a substance (the response) to elapsed time (the predictor). To illustrate, consider the example of long-term recovery after discharge from the hospital from page ...How do you calculate exponential regression? First, you need to have data pairs of the form \((X_i, Y_i)\). Normally, when these data are at least loosely clustered around a straight line, a linear regression model is calculated by computing its coefficients via the Least Squares method. This is the approach that is used on the website to find the coefficients for exponential regression ... See the following webpage for how to calculate R^2 Regression analysis in Excel Charles.
