A computer-readable medium having computer-readable instructions stored thereon, which, when executed by a computer arrangement, configures the computer arrangement to perform a new plurality of steps. Those steps include retrieving data from a database. The data is associated with a plurality of assets, and the data for each asset includes information associated with the plurality features of the asset. The computer arrangement also groups the plurality of assets into at least one cluster based on the data and determines an associated hypothetical standard metric. A hypothetical standard metric comprises at least one of a Z-score corresponding to a deviation to a norm of the grouping and a curved line fitting. The computer arrangement also determines a degree of difference between each of a plurality of assets in the hypothetical standard metric and removes at least one asset of the plurality of assets to decrease the degree of difference.
