Definition Of Exponential Regression

We use the command expreg on a graphing utility to fit an exponential function to a set of data points.

Definition of exponential regression. We use the command expreg on a graphing utility to fit an exponential function to a set of data points. Exponential regression is used to model situations in which growth begins slowly and then accelerates rapidly without bound or where decay begins rapidly and then slows down to get closer and closer to zero. If the curve decreases it s called exponential decay. The value of r 2 varies between 0 and 1.

Calculus definitions an exponential model has a distinctive upward or downward curve that increases or decreases sharply and smoothly. An exponential regression is the process of finding the equation of the exponential function that fits best for a set of data. If the curve increases then it s exponential growth. Exponential regression exponential regression is used to model situations in which growth begins slowly and then accelerates rapidly without bound or where decay begins rapidly and then slows down to get closer and closer to zero.

Growth is the exponential counterpart to the linear regression function trend described in method of least squares.
