Claim One:
1. A computer system for breaking a time series into a plurality of discontinuous trends, the system comprising: an input means for inputting time series data to a computer, the time series comprising a plurality of data elements, at least a portion of which represents a trend which is generally increasing or decreasing; a memory means for storing the time series data; a processing means for selecting a plurality of sets of trend determination parameters for the time series, each set of trend determination parameters comprising at least one window size, such that the window size defines a number of adjacent data elements from the time series to be used to generate trends; selecting a useful group of sets of trend determination parameters for the time series from the plurality of sets of trend determination parameters, such that the useful group of sets includes at least one member; processing the time series with each member of the useful group of sets of trend determination parameters to generate a set of trends and trend attributes for each member; evaluating the trend attributes for each member; selecting at least one set of trends; and an output means for outputting the set of trends from the computer.
