A Brownian bridge is a continuous-time stochastic process B(t) whose probability distribution is the conditional probability distribution of a standard Wiener process W(t) (a mathematical model of Brownian motion) subject to the condition (when standardized) that W(T) = 0, so that the process is pinned to the … See more A standard Wiener process satisfies W(0) = 0 and is therefore "tied down" to the origin, but other points are not restricted. In a Brownian bridge process on the other hand, not only is B(0) = 0 but we also require that B(T) = … See more For the general case when B(t1) = a and B(t2) = b, the distribution of B at time t ∈ (t1, t2) is normal, with mean $${\displaystyle a+{\frac {t-t_{1}}{t_{2}-t_{1}}}(b-a)}$$ See more WebJan 24, 2024 · The Brownian Bridge Joint Max Position Distribution.
