WebSep 12, 2024 · The First Order Difference It is the most simple filter among all of them. In the output, it gives a time series which is basically a difference between the present variable and the previous time step time variable. This is a commonly used method because it causes the removal of unit root components from a time series. WebThe first difference is given by out [i] = a [i+1] - a [i] along the given axis, higher differences are calculated by using diff recursively. The number of times values are differenced. If zero, the input is returned as-is. The axis along which the difference is taken, default is the last axis.
