Digital Signal Processing (DSP) filter
DSP (digital signal processing) filters are commonly used on input series to reduce their noise. This is typically a more rigorous option to "smooth" a series than using a rolling aggregate.
Quiver includes three separate filtering algorithms/prototypes:
For each algorithm, a filter response must be selected from the following options:
Input type
Time series
Output type
Time series
