Research On Application Of Regression Analysis In The Large Number Of Similar Equipment Evaluation

Along with the rapid development of our country's economy,all kinds of economic activity have increasing frequently,assets appraisal as a professional service is also more and more applied in the market.With the development of market economy,there are more and more reques for the asset evaluation work,only by improving the work efficiency,the evaluation work can accomplished the demand of the development of market economy.Machinery and equipment assessment as one of the core content of assets evaluation,play an important role in zhe approved value of Machinery and equipment,promote trade,implementation,evaluation purpose,etc.Now our country asset classes is very complicated,management of the second-hand machinery and equipment trading market is not perfect,And the machinery and equipment assessment has not yet formed a set of scientific and reasonable evaluation system,all of these factors has brought certain difficulties to machinery and equipment assessment work.Assets evaluation work in machinery and equipment occupy larger proportion in assessment business,Machinery and equipment assessment has the characteristics of many varieties,large quantity,strongly professional,which make the evaluation more trapped.Although the evaluation methods of machine equipment in constant development fast,Machinery and equipment assessment practice now still ues the replacement cost method as the main method of machinery and equipment assessment.There are large number of devices involved in the practical work of Machinery and equipment assessment,Considering with the cost,The asset appraisal company will not evaluate same equipments one by one,but by extract part of the machinery and equipments to assess,then predict the value of all the same kind equipment evaluation.Sampling method in the practical work of has no standard and calculation method is very simple,it is easy to cause error for zhe assess.This paper will combine the machine equipment evaluation with regression analysis technology,According to the principle of regression analysis and correlation theory of the replacement cost method,adopting regression analysis technology to valuing a large number of similar machines,and regression analysis the feasibility and applicability in a large number of similar equipment evaluation.First,this paper make some simple introduction in the machinery and equipment assessment involves three based on the three main evaluationmethods and steps,At the same time make a simple overview principle of multivariate linear regression analysis.Secondly,based on the assessment theory and practice related a lot of the status quo and problems in similar machinery and equipment assessment and analysis the cause.Then,using the assessment data to validated the feasibility of multiple linear regression analysis in a large number of similar of machinery and equipment assessment,through the selection of data,multiple linear regression model and model test,proved that the regression analysis technique can be used in the assessment.Finally,make an example test the applicability of the regression analysis method in a large number of similar machinery and equipment evaluation,Calculating regression prediction assessment evaluation results and the traditional method evaluation results,ues the two results Compared with the accurate evaluation results respectively,finally shows the result of regression forecast is more close to the total cost of the accurate assessment results,proved that the method in this paper is scientific and applicable.
