WebApr 8, 2024 · De Finetti's theorem, also called the de Finetti-Hewitt-Savage theorem, is a foundational result in probability and statistics. Roughly, it says that an infinite sequence of exchangeable random variables can always be written as a mixture of independent and identically distributed (i.i.d.) sequences of random variables.
Web漂移项（英語： drift term ）表示随机过程中，时间序列的正或负趋势。 当随机变量是金融资产时，作出正的漂移假设是合适的，因为风险资产应该提供正的收益以补偿投资者所承担的风险，这样漂移类似于期望收益。 變量 的漂移参数 表示每段小时间 中，因漂移產生的变化為 。 WebA sequence of random variables is called exchangeable if the joint distribution of the sequence is unchanged by any permutation of the indices.
