1. A system for processing a stream of data events, comprising:

  • at least one computing device, including;

    a real time statistical processing system for updating a first and a second running value each time a new data event is obtained, wherein the first and second running values are calculated based on a previously calculated running value and a difference DV between a current data event value (Vi) and a previous data event value (Vi−

    1
    ), wherein the first running value RDVi=(1−

    K)*DV+K*RDVi−

    1
    and the second running value RDVVi=(1−

    K)*DV2+K*RDVVi−

    1
    in which K is a half-life based smoothing factor that dictates a period over which a decline in data event values is analyzed, and wherein a third running value RSDD comprises a running standard deviation computed by the real time statistical processing system as follows;

    RSDD=sqrt(RDVVi

    RDVi2); and

    an analysis system for analyzing each running value after it is updated to detect trends in the stream of data events.
