Tests of the linear models in a new system approach in estimate theory

The results of direct tests on the linear deterministic models recently pro posed in estimate theory are presented. In this work, we test the class of linear model to a case study, cheking the results of analysis according to the comparison approach. The method helps to define the reliability of the appraisal estimate interpreted as the most probable selling price. Our resu lts show that the performance of the program strongly depends on the select ion of units of comparison and also on the criterion adopted to remove the tails of the probability density.
