若干概率分布的正態(tài)逼近
若干概率分布的正態(tài)逼近
摘 要
在整個概率論與數(shù)理統(tǒng)計中,各種分布起了重要的作用,其中以正態(tài)分布最為重要.許多重要的概率分布都與正態(tài)分布密切相關(guān);此外,很多重要分布的極限分布,在1定條件下也都是正態(tài)分布;有些隨機變量其分布雖然未知,但是只要滿足很1般的條件,其極限分布也是正態(tài)分布.本文主要介紹了若干概率分布的正態(tài)逼近,探討了他們的應(yīng)用,充分說明正態(tài)分布在概率統(tǒng)計中的重要地位.

The normal approximation of some probability
ABSTRACT
Various kinds of distribution have played a very important role in the whole probability theory, among them it is most important to regard normal distribution as.a lot of important .many important probability distribution all have something to do with normal distribution; In addition, a lot of important limit distributed is distributed, are all normal distribution under certain condition; Some random probability distribution of variable unknown even, must meet general terms very, it is normal distribution too that its limit is distributed. In my this paper, i introduce the normal approximation of some probability, and discuss the application of them to speak volumes for the important status in the probability statistics of normal distribution.
Key word:The typic Distribution; Eigenfunction; Normal approximation; The application of the normal approximation
