In other words, it was not a random drawing from a distribution of events with a fat tail but actually predictable in advance given the rising macro and financial risks and vulnerabilities.
换句话说，它并非带有肥尾的一系列离散事件的随机结果，而是在事先观察到上升的宏观及金融风险后完全可以预见到的。
Some statistical test methods on "fat tail" distribution of time series are obtained by using properties of extreme value theory and extreme index estimator under large sample.
使用极值理论和极值指数估计量的性质，在大样本的情况下得到序列分布“肥尾”现象的检验方法。
Empirical evidences show that the distributions of high frequency time series are "fat tail" type distribution rather than normal distribution with "light tail" as those in traditional modeling.
经验表明高频时间序列的分布常是“肥尾”型的，而非传统建模中的“薄尾”型的正态分布。
Operational risk is a kind of low frequency and high severity loss risk. Its loss distribution shows fat-tail. It is often underestimated by using usual methods for risk measurement.
操作风险发生的频率较低，但可能会引起巨大的损失，其损失分布具有鲜明的厚尾性，因此应用通常的风险计算方法往往会低估风险。
