WebFeb 9, 2024 · If the data is 12-month seasonal, substracting the series with a 12-lag difference series will give a “flatter” series Logging : in the case where the compound rate in the trend is not due to a price index (ie the series is not measured in a currency), logging can help linearize a series with an exponential trend (recall that log(exp(x)) = x).

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. A related topic is regression analysis, which focuses more on questions of statistical inference such as how much uncertainty is present in a curve tha… WebIn regression analysis, curve fitting is the process of specifying the model that provides the best fit to the specific curves in your dataset.
