Abstract

Abstract The subject of the considerations presented in the article is the question of the criteria according to which the comparables, in the market value estimating process, should be selected. As the most important in the selection of comparative properties, the factor of similarity in relation to the subject property (measured by the Euclidean distance) was considered. As the key issue, the similarity assessment criterion and the influence of the adopted critical value of this criterion on the accuracy of estimates were chosen. The analysis of the above was carried out with taking into account the role of the significance of independent variables (measured by their correlation with the vector of the dependent variable). The results of the simulation tests carried out in the variants set by the criteria adopted were presented. On this basis, it has been shown that there is a potential most relevant solution in the collection of obtainable estimation results. This solution corresponds with the smallest sum of the differences of model prices (accepted as known) and corresponding estimates. The found minimum occurs for a specific layout of the above criterion values only.

可比品选择标准对物业价值估算准确性的影响分析
摘要本文研究的主题是在市场价值评估过程中选择可比物的标准问题。在比较性质的选择中,最重要的是考虑与主体性质的相似性因素(用欧几里得距离来衡量)。选取相似度评价准则以及该准则所采用的临界值对估计精度的影响作为关键问题。在进行上述分析时,考虑了自变量的显著性作用(通过它们与因变量向量的相关性来衡量)。给出了在所采用准则所设定的变型中进行的仿真试验结果。在此基础上,已经表明,在可获得的估计结果的集合中存在一个潜在的最相关的解决方案。此解对应于模型价格(已知接受)和相应估计值差异的最小和。找到的最小值只出现在上述标准值的特定布局中。
