Economic models are by definition incomplete representations of reality. Modellers typically abstract from many features of the data in order to focus on one or more components of interest. Similarly, when confronting data, empirical economists must somehow isolate features of interest and eliminate elements that are a nuisance from the point of view of the theoretical models they are studying. Data filters are sometimes used to do that.
