A proof is given to show that the limit distribution of Poisson distribution is normal d istribution.
本文主要阐明概率论中三个重要分布之间的关系 ,重点证明了普阿松分布的极限分布是正态分
By taking advantage of the characteristics concerned with difference-quotient and the Poisson distribution, Mr.
本文对Feller在[1]中利用差商和普阿松分布的有关性质,证明的广义泰勒展式进行了推广,放宽了定理中对函数有界的要求,扩大了定理的使用范围。
So, Poisson distribution is often employed to approxi-mate the binomial distribution to simplify the calculation.
在概率论中有大量的实际问题需要用二项分布来求解,但二项分布的计算有时相当麻烦,计算量相当大,往往同普阿松分布来逼近二项分布以简化计算。
For fear of Lü Bu in Xuzhou who might lend Liu a hand, Yuan wrote Lü a letter, together with many food supplies as gifts, asking him not to help Liu.
