WebFitting a model with a single sinusoidal wave at this estimated frequency should already explain a lot of the variation in your data. You can add a trend term to this and other … 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 approximately fits the data.
