WebNov 6, 2024 · Curve fitting is the process of finding a mathematical function in an analytic form that best fits this set of data. The first question that may arise is why do we need that. There are many cases that curve fitting can prove useful: quantify a general trend of the … Fitted curves can be used as an aid for data visualization, to infer values of a function where no data are available, and to summarize the relationships among two or more variables. Extrapolation refers to the use of a fitted curve beyond the range of the observed data, [16] and is subject to a degree of … See more 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.
