假定隨機變量為單峰分布,眾數(shù),且滿足,,研究了三段線性函數(shù)的概率上界與下界,其中:;.給出了單峰分布下三段截尾變量概率邊界的估計,進一步深化了小值概率理論的原有認識.

小偏差概率估計問題的研究歷史悠遠,從Chebyshev到Stieltjes[1],提出了切比雪夫不等式并給出了證明過程.后來Karlin S[2],Isii K[3]在概率的研究工作上也做出了非常杰出的貢獻.近期,Popescu I[4]得到了單峰分布下隨機變量在時,的上確界.在國內(nèi),也有相關(guān)研究[5-8],這些研究使概率理論的應(yīng)用價值得到了非常廣泛的推廣.

Supposed random variablesis the unimodal distribution.Modeand the random variableswith,,mainly studied the problem of estimating on upper bound and lower bound of probability for three-piece truncated random variables for estimations ofwith,given.Gave the estimates on bounds of probability for three-piece truncated random variables of the unimodal distribution,the result improves the original understanding of probability theory.
