A computer program system for the analysis of equispaced time series
W. Martin, Klaus Brinkmann · Journal of Interdisiplinary Cycle Research · 1976
A computer program system for the analysis of equispaced time series is presented which includes plotting of several time series, smoothing of one time series with arbitrarily centered symmetric moving average processes, removing trends out of one time series by a stepwise linear approximation to the trend, calculating periodograms, normanalysis, estimates of powerspectra, and the application of an algorithm based on average signals. The system is proposed to be an adequate tool for detecting hidden periodicities of real time series, and for preparing an analysis in testing the methods on system generated artificial time series. It is fitted to computer dialog systems as well as to computer batch systems.
