對隨機變量間相依性的度量But my focus was specially laid on the decision - making of investment under uncertainty and with competition, i first. extend the basic model of dixit & pindyck ' s by allowing the relevant parameter to be a random variable, then proposed an numerical example to show how to solve this model, i gave the algorithm and did the comparative static analysis, finally i developed a model of duopoly under uncertainty, considering the competition between the firms explicitly, using roa, i calculated the two firm ' s values respectively when they take different roles - to be leader or follower, and then checked the possible equilibriums
本文的重點是考察在同時存在不確定性和競爭的情況下，如何用實物期權的理論估算投資項目的價值，為此，文中發展了兩個模型，第一個模型是對dixit & pindyck的模型的擴展，它通過一個相關的隨機變量來考察競爭對項目價值的影響，但沒有考慮企業間的相互博弈，文中給出了一個例子詳細地說明了該模型的求解並做了敏感性分析；第二個模型是一個不確定情況下的雙寡頭模型，文中給出了用實物期權方法計算的兩企業在處于領導者和跟隨者兩種不同境況時的價值，並將企業間的相互博弈考慮在內，考察了可能的均衡狀態。An estimator is a random variable.

隱馬爾可夫模型可應用於弱相依隨機變量的建模上，也可用作研究發音過程、神經生理學與生物遺傳等方面的工具。The limit theory of law of the iterated logarithm have received more and more attentions, especially about identical independent random variables. but up to now, the studies are only for partial sums and, have n ' t shown any concern on the special finite partial weight suras. however, the partial sums and partial weight sums not only have the osculating aspects, but also have essential difference between them. so the studies for these play an important role in theoretical and applied setups
因此對重對數律的研究引起了國內外學者的興趣，對獨立同分佈的隨機變量，許多學者做了大量的研究工作，但迄今為止這方面的研究仍限於部分和數列的重對數律，很少涉及到特殊加權和的領域，而部分和與加權和之間既有密切聯系，又有本質不同，因此，這一問題的研究具有一定理論意義和應用價值。By contrast, the paper calculated the reliability index of the abutment after changing variable quotiety of the stochastic variable
