As a result, in this paper, the method of risk budgeting is implemented on the basis of relative risk, and through the use of some relative concepts such as marginal tracking error, position based on benchmark, aggressive factor and aggressive beta coefficient, we constitute two optimal models which respectively allocate risk to portfolio manag.

BETA Coefficient and Audit Price:Empirical Evidence from China s List Companies;

Study on the Existence of Beta Coefficient and Its RelatedCharacteristic in Securities Market;

Moreover,Beta coefficient test indicates that regional economic cooperation organization is the most important factor which influences China s international trade.

Beta-function measurement and analysis at HLS;

By estimating the weight function and introducing the Beta function, a Hilbert-type integral inequality with a parameter and a best constant factor is built.

This paper deals with an extension of Hardy-Hilbert s type inequality with a best constant factor by introducing a parameterλand using the Beta function.

By introducing parameters and the Beta function,we give an extension of the Hilbert s type inequality with a best constant factor.
