利用上鞅的性质,研究投资者关于收益向量的估计分布与真实分布之间有偏差时投资者平均收益的极限性质,得到了用不等式表示的强偏差定理.
Using the properties of submartingales, this paper obtained a strong deviation theorem about the limit properties of return rate when there are deviations between the estimated and the real distributions of the return rate. The conclusions are represented by inequalities.
