Book excerpt: First published in 1997, this volume emerged in response to the need for material on the research, development, use and application of mass appraisal techniques for ad valorem property tax systems. The primary paradigms discussed include regression, base home technique, adaptive estimation procedure and artificial neural networks. Intending to address a wide range of property types, the authors explored residential, condominiums, retail, office and industrial property as well as agricultural and forestry land.
