A filter based fisher g-test approach for periodicity detection in time series analysis
Periodicity is an interesting property of many time series data sets. A period can be defined as a self repeating pattern. This pattern provides useful information about the inherent structure in cyclic data set. In this paper, a filter based Fisher g-test approach is introduced. The filtering approach is based on the singular spectrum analysis. The power and running time of the proposed filter based approach are...
