A method involves identifying account data of an entity for a present time period, where the account data includes more than one first data value, creating a comparison group for the entity. The comparison group includes more than one second data value, the account data of the entity includes the second data values, and the second data values originate from a prior time period. The method further involves selecting, from the first data values, a subset of the first data values, selecting, from the second data values, a subset of the second data values, identifying, by accessing a library including anomaly detection methods, an anomalous value within the subset of the first data values by comparing the subset of the first data values with the subset of the second data values, selecting an action in response to identifying the anomalous value within the subset of first data values, and initiating the action.
