Claim 10:
11. A system comprising:
a non-transitory storage medium storing computer program instructions;
a processor configured to execute the computer program instructions to cause the system to perform operations comprising:
obtaining an anomaly detection model comprising a statistical tree structure associated with an input data feature, the statistical tree structure comprising a plurality of nodes corresponding to a set of cohorts, each cohort comprising a set of statistic values of the input data feature associated with a set of system users, a variance of values of the input data feature and respective cohorting data features;
traversing the statistical tree structure with a target dataset from a first node to a leaf node to form a set of target cohorts and determine a target statistic value of the input data feature at the leaf node;
determining that the target statistic value is not within a pair of thresholds; and
flagging a data field of the target dataset as an anomalous field.
