The Analytical Foundations of Adjustment Grid Methods
澄清了房地产评估中三种调整网格方法的分析基础，并介绍了估计调整因子和加权方案的方法，指出网格预测可能优于纯回归预测。
Within the market data approach to real estate appraisal, two basic types of analysis generally are used: (1) regression analysis; and (2) adjustment grid methods. The focus of this paper is on the adjustment grid methods. Three such methods are identified in the appraisal literature, but their analytical foundations are not clearly presented. The primary objective of this paper is to clarify the analytical foundations of each method. In addition, various ways to estimate the adjustment factors needed to apply the grid methods and a weighting scheme for reconciliation of indicated values are presented. Also, the possible advantage of grid‐based over purely regression‐based predictions is identified.
