查询词典 random deviate

I. d. Bernoulli random variables. First, we can get the upper bound with order from Chebyshev inequality. Second, a better upper bound was gotten with the new inequalities, which can fasten the convergence rate.

并对服从两点分布的独立随机变量X1，X2，…，X进行研究，首先利用Chebyshev不等式得到随机变量偏离方差ES的上界，但它只有阶的收敛速度，然后利用新的不等式得到一个新的上界，它有更快的收敛速度，这在探讨收敛速度时有着重要的理论意义。

Methods: Consult VP diagnosis standard of American psychiatry institute what WHO promulgated, we chose 80 VD sufferer. We adopt study method of random and comfort drug comparison, both blind method to dose and front and bank of oneself chiasma test. We chose MMSE and ADL to evaluate curative effect through comparing Statistic mark before cure and after cure. Results: We had treated 72 VD sufferer on Jiannaoyizhi capsule. In these patients, there are 15 obvious efficiency, 38 efficiency and 19 inefficiency. The total efficiency is 73.61%. It has obvious reform action on cognizing obstacle and behavior.
