Nettet31. okt. 2024 · Line of Best Fit (Least Square Method) A straight line that best approximates the given set of data is known as a line of best fit. It is employed to investigate the type of relationship between two variables. In this case, we only take the two-dimensional case into account. NettetCurve 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. [4] [5] Curve fitting can involve either interpolation , [6] [7] where an exact fit to the data is required, or smoothing , [8] [9] in which a "smooth" function is constructed that approximately fits the data. dunn wheel repair
