Overview Method Settings Example Overview The Seasonal adjustment MA analysis removes the seasonal pattern from a series using moving averages. The algorithm used is not as advanced as in Seasonal adjustment Census X-13, but is much faster and easier to use and works well in many cases. The method works by calculating a seasonal factor … Continue reading “Seasonal adjustment MA”
Overview Settings Examples Questions How to find a trend with Detrend analysis? Overview The Detrend analysis removes trends from time series by either subtracting or dividing, depending on the chosen method. This is useful when you want to concentrate on the cyclical component of a series. The cyclical component is one of four components of … Continue reading “Detrend”
