查询词典 indefinite total variation

Regional variation difference was very large with more ice in the eastern Antarctic, obviously less ice in the west Antarctic, both sides of the Antarctic Peninsula, especially in the Weddell Sea and the Bellingshausen Sea. The sea ice variation trend in the eastern and western Antarctic is always in opposite phase.

Chapter 4 is the central part of this dissertation, where the bayes bilateral integrated moment is established on the base of Bayes theory, downside risk and upside potential. According to the variation coefficient which is based on the M-V approach, we substitute lower partial moment for the numerator of variation coefficient, and use higher partial moment as the substitute of the denominator, then we got bilateral integrated moment. Subsequently, through Bayes method we can absorb new information, revise the return distribution from transcendental distribution to posterior distribution, so we got bayes bilateral integrated moment.

第四章是本文的核心部分，在简要介绍Bayes理论、下方风险和上行潜能的基础上，仿照来源于Markowitz的均值——方差理论的变异系数方法，以下偏矩取代其分子部分，以上行潜能取代其分母部分，设计了双侧综合矩方法，接着再引入Bayes方法，吸纳新信息，采用后验概率，设计了Bayes双侧综合矩方法，并在理论上说明了新方法的优越性。
