Patent ID: 7346471

Claim:
A system that facilitates data anomaly mitigation, comprising: a receiving component that receives at least one historical time series relating to an Internet web traffic data set; a statistical modeling component that constructs and/or obtains at least one predictive model for each data slice of the historical time series, at least one data slice is a time period of Internet web traffic that is a function of a day, a week, a month, and/or a year; an outlier determination component that detects outliers in the historical time series utilizing at least one predictive model, wherein the outlier determination component employs at least one predictive model to facilitate determination of an expected value of an actual historical time series value and utilizes a multiple of a standard deviation of the actual historical time series value to the expected time series value to detect an outlier, and an outlier replacement component that replaces at least one detected outlier with its expected value to facilitate in mitigating an effect of the outlier on the historical time series.
