Analyse stationary time series data.
Series reads time series data from standard input and outputs various statistics on standard output.
The data read from standard input consists of one or more realizations of the time series. The different realizations are separated by blank lines. At lag i, the cumulative autocorrelation is one plus twice the sum of the autocorrelations from 1 to i. The default maximum lag is the maximum length of any of the realizations minus one. If a presumed mean is specified, it is used rather than the estimated mean when calculating the autocorrelations, and the displayed variance, and the variance used to normalize the autocorrelations.
