SPECTRAL DISCRIMINATION FOR TWO GROUPS OF TIME SERIES
Javier Alagón · Journal of Time Series Analysis · 1989
Abstract. The problem of discriminating in the frequency domain between two groups of Gaussian stationary time series is examined. A test aimed at detecting differences between the windowed spectra of the two groups is used. The effect of windows on the resulting quadratic discriminant function is considered. Two examples taken from seismology and neurology are given.
