description A method for identifying anomalies in time series data, the method comprising the steps of computing parity vectors for one or more data points in a predetermined sample of data points in the time series, the parity vector representing redundancy between an estimated true value and an error term for each of the said one or more data points, evaluating the parity vectors to determine a set of the parity vectors in a selected direction; and evaluating a statistical distribution of the set according to a predetermined criterion to determine a data point to be corrected whose parity vectors satisfy the criterion in the distribution.
