Problems solved by technology
[0003] In the existing technology, the data sizes of different indicators vary greatly, which requires setting thresholds for each indicator, which makes it difficult to implement the threshold judgment method; at the same time, even for the same indicator, the corresponding indicators may have different thresholds at different times , which further increases the difficulty of the threshold judgment method. If the threshold is set unreasonably, it will also make the judgment of abnormal data inaccurate.

The invention discloses a method and a device for determining abnormal index data. The method comprises the steps of determining a to-be-evaluated index, acquiring current index data of the to-be-evaluated index, acquiring historical data of the to-be-evaluated index according to a statistics time point which corresponds with the current index data, successively determining the average level and the fluctuation level of the to-be-evaluated index according to the historical data of the to-be-evaluated index, and determining an abnormity index of the to-be-evaluated index according to the average level of the to-be-evaluated index. Through periodically extracting the historical data of a time segment when data points of the index arrive, a periodical effect of the data can be eliminated, and an abnormity coefficient is dynamically generated through integrating the average level and the fluctuation level of the to-be-evaluated index. Personnel can determine the abnormity degree of the current to-be-evaluated index just through comparing the abnormity index of the to-be-evaluated index with a constant 1 / -1.
Description
technical field [0001] The invention relates to the technical field of data analysis, in particular to a method and device for determining abnormal index data. Background technique [0002] To judge the abnormal data of an indicator, the common method is to set the highest threshold and the lowest threshold, and the data that is not within the range of the highest threshold and the lowest threshold can be judged as abnormal data. [0003] In the existing technology, the data sizes of different indicators vary widely, which requires setting thresholds for each indicator, making it difficult to implement the threshold judgment method; at the same time, even for the same indicator, the corresponding indicators may have different thresholds at different times , which further increases the difficulty of the threshold judgment method. If the threshold is set unreasonably, the judgment of abnormal data will also be inaccurate. Contents of the invention [0004] Embodiments of th...
