  • Method, data processing program and computer program product for time series analysis
    Patent number: 8200454
    Abstract: Method, apparatus, and system, including computer program products, implementing and using techniques for time series analysis, wherein the time series exhibit trend and/or seasonality. Model parameters of the time series data are determined by selecting and/or suggesting a most appropriate combination of trend and seasonality of the time series data based on analysis of variances of transformed time series data.
    Type: Grant
    Filed: May 13, 2008
    Date of Patent: June 12, 2012
    Assignee: International Business Machines Corporation
    Inventors: Ansgar Dorneich, Maik Goergens, Andrzej Toroj
  • Method, data processing program and computer program product for determining a periodic cycle of time series data
    Patent number: 8055465
    Abstract: Method, apparatus, and system, including computer program products, implementing and using techniques for determining a periodic cycle of time series data. A frequency spectrum of the data is provided. The frequency spectrum is processed using at least one of the following steps, resulting in a processed frequency spectrum: filtering the frequency spectrum for reducing noise of the data, truncating the frequency spectrum at low frequencies, and weighting high frequency contributions over low frequency contributions of the frequency spectrum. A periodic cycle is extracted based on the processed frequency spectrum.
