摘要: Bootstrap method will largely improve the accuracy of risk measurement, which be used to calculate the value at risk of securities investment funds. The application of the Bootstrap method with GARCH-based risk measurement model, not only consider the fund’s data auto-correlation and the time-variable variance characteristic, but also very well simulate the distribution of the residual. The theoretical analysis and empirical analysis indicate that this flexible parameter-nonparametric mixed risk measurement model can improve estimation precision of VAR.
