The Attribute Profile method compares Attributes Of Interest value relationships. Suppose, for example, that the attributes are market-share captured and pet-ownership rate. If the target Input Features To Match has a pet-ownership rate that is twice as large as the market-share captured, the tool will look for candidates with that same relationship. If the target has a 40 percent pet and 20 percent market share, candidates with 10 and 5 or 90 and 45 would be very similar matches.
Include at least two Attributes Of Interest or select a different Match Method.
