The Errors Estimate of the Multistage Combined Investment Risk Assessment

Abstract

Investment risk is economic development faced serious risk. The multistage combination investment risk assessment (MCIRA) can reduce the assessment error, but how to survey the error which produces by the MCIRA models, has the important significance. From theoretical side, the errors upper-bound of the MCIRA models is determined in this paper. We also give the relationships between the errors of the general MCIRA models, the simple average models and the errors of each investment risk assessment model in the combination.
