Methods and systems for identifying device models or accounts exhibiting outlying behavior are disclosed. For a method of identifying a device model exhibiting outlying behavior, a processor may receive a color impression count, a monochrome impression count and either a device model for each of a plurality of devices. A proportion of color revenue may be determined for each device based on the color impression count and the monochrome impression count. The processor may determine, for each device model, a distribution of the proportion of color revenue for the one or more devices having the device model and may automatically identify one or more distributions of the proportion of color revenue exhibiting outlying behavior. Each distribution is associated with a device model.
