 ABSTRACT = {There is no generally accepted procedure for identifying ultradian
             pulsations in hormonal time series. We suggest an approach based on
             removing long-term trends, such as diurnal rhythms, from the series
             of observations; identifying peaks in the residual series; and
             resolving each peak, if appropriate, into overlapping secretory
             episodes. The first step uses a robust smoothing technique to
             generate a smoothed series that omits peaks or trends with time
             constants less than 6--12 h. The smoothed series is subtracted from
             the original, and in the second step their difference, the residual
             series, is examined for the presence of peaks. The standard
             deviation of the assay is calculated at each point, and the
             residuals are rescaled in terms of this unit. Peaks are identified
             as individual subseries elevated above the base line of duration
             $n$, all the points in which have magnitude at least $G(n)$, where
             the values of $G$ are cut-off criteria based on the width of the
             peak. Thus the algorithm selects both narrow high peaks and broader
             peaks that may be lower. The user selects the $G(n)$ for each
             hormone based on theoretical considerations or a set of calibration
             data series. Points that meet these criteria are identified as
             belonging to peaks and flagged. To assure that the smoothing
             process is not influenced by runs of closely spaced peaks, these
             flagged points are then assigned a reduced weight, and the
             smoothing is repeated; the revised residuals are then reexamined.
             After these two steps are iterated until there are no further
             changes, each peak is examined once more to determine whether it
             can be resolved into more than one overlapping peak. Finally, the
             process collects statistics on the average frequency and amplitude
             of the peaks. We have developed computer programs to carry out
             these algorithms.},
