The Design On Evaluate System Of Fund Based On The Principal Component Regression

In the 90’s of the last century, the “securities investment fund management approach “(Provisional) was published, passed through about 20 years development and improvement, Chinese fund investment industry took shape of scale. Especially after the September 2001 China began issuing open-end fund, the growth of China’s investment fund industry achieved unprecedented strides across. In the financial prosperity of the country, the fund management system is very advanced, and the stock fund, bond rating agencies have become common pillar of capital market credit rating jointly.

The content covers screening coefficient of principal component rating method, the practical operation model of construction process and mold.Three: analysis of user needs and technical means, including analysis of supply and demand on the operating platform, and technology required operating platform planning. Four: the planning of investment fund rating system established on the main components of decomposition, covering SQL planning, planning software interface, data module planning and a series of design.Five: the implementation of system function and simulation test, covers the operation interface of the operating software and the evaluation ofsystem.Six: the concluding part.
