ABSTRACT:
To detect a change in data produced by a system, predicted data values for plural time points are computed. Actual data values for the plural time points are received, and residual values are derived from differences between the predicted data values and actual data values. Based on the computed residual values, a time point at which the change in data occurred is determined.
