The financial asset's yield distribution has some typical characteristics such as leptokurtic, fat tail, skewed and Asymmetry,but the traditional normal distribution,t distribution,SKST distribution cannot fully describe these characteristics,which has influenced the efficiency of parameter method of VaR models based on them.In recent years,the theoretical circle has proposed AEPD,AST,ALD and other distributions to improve the description of the financial asset's yield distribution.The CSI 300 index is ch...
