Witryna13 lut 2024 · Determine that linear model, e.g., with the method of least squares. Transform the data along with the model back to the original form. Exponential regression formula for the data (x, y) is: y = exp (c) × exp (m × x), where m is the slope and c is the intercept of the linear regression model fitted to the data (x, ln (y)). WitrynaCurve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints. Curve fitting can involve either interpolation, where an exact fit to the data is required, or smoothing, in which a "smooth" function is constructed that approximately fits the data. A related …
