WebThus, the Brownian bridge can be defined as a Gaussian process with mean value 0 and covariance function s (1-t), s ⩽ t. This leads to an alternative approach to obtaining such a process. Proposition 10.1. If {X (t), t ⩾ 0} is standard Brownian motion, then {Z (t), 0 ⩽ t ⩽ 1} is a Brownian bridge process when Z (t) = X (t)-tX (1). Proof WebThe inverse Gaussian bridge can be used with other variance reduction techniques to achieve even greater speed-ups. Other authors have exploited the standard Brownian bridge. Beaglehole, Dybvig and Zhou (97) [6] use a knowledge of the distribution of extremes of a Brownian bridge to signiﬁcantly speed up a Monte Carlo method for pricing

The Brownian bridge is (like the Ornstein–Uhlenbeck process) an example of a Gaussian process whose increments are not independent. The fractional Brownian motion is a Gaussian process whose covariance function is a generalisation of that of the Wiener process. how to make a batch file run as administrator
