Web高斯分布和Dirac-δ函数分布. 相空间分布,主要指的是位置-动量(或者时间-能量)构成的相空间,比如我们熟悉的Wigner函数分布。就拿高斯分布来说,它在相空间中的Wigner函数还是高斯型的,即不管你从动量坐标还是位置坐标来看它都是高斯的。 WebNov 3, 2024 · 带有Student-t改进的GARCH(1,1)模型基于Nakatsuma(1998)的工作,由Metropolis-Hastings(MH)算法组成,其中分布是根据平方观测值由辅助ARMA过程构建的。 这种方法避免了选择和调整采样算法的耗时且困难的任务,特别是对于非专家而言。 list of church officers
