在μ的先验密度为高斯分布,罚函数为二次函数或Dirac-delta函数的条件下,我们显式地解决了分数布朗运动漂移参数μ的贝叶斯序贯估计问题。在这种情况下,最佳停止时间是确定的。
Abstract We solve explicitly a Bayesian sequential estimation problem for the drift parameter μ of a fractional Brownian motion under the assumptions that a prior density of μ is Gaussian and that a penalty function is quadratic or Dirac-delta. The optimal stopping time for this case is deterministic.
