    SAS Note: 002380 ***ALERT NOTE*** Product: ETS

    Title:
    Incorrect results produced for large time series

    Keywords:
    INCORROUT INCORRSTAT FOURIER SPECTRA TRANSFORM LARGE

    The Fourier coefficients and other spectral analysis statistics computed
    by PROC SPECTRA may be computed incorrectly if the length of the input
    time series is greater than 20,000.

    Fourier coefficients for affected time series can be computed correctly
    using the FFT function in SAS/IML.
