Nettet6. okt. 2014 · Step Two. The system conducts initialization for the specified model and the test model (for example, in forecast strategy 54, the selected model is seasonal, and the test model is a trend model). For initialization to occur, a sufficient number of historical values need to be present in the system. 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.
