Curve fitting parameters
WebThe Curve Fitting Toolbox supports these goodness of fit statistics for parametric models: The sum of squares due to error (SSE) R-square Adjusted R-square Root mean squared error (RMSE) For the current fit, these statistics are displayed in … Curve 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 … See more Most commonly, one fits a function of the form y=f(x).
