Webb1 juni 2016 · Let {X(t), t ⩾ 0} be a standard Brownian motion. That is, for every t > 0, X(t) is normally distributed with mean 0 and variance t. Then {X(t), 0 ⩽ t ⩽ 1 X(1) = 0}, known as the Brownian bridge, is a Gaussian process. That is, for every 0 < t < 1, it is multivariate normally distributed. Webb8 maj 2024 · The Brownian Bridge is a classical brownian motion on the interval [0,1] and it is useful for modelling a system that starts at some given level and it is expected to return to that same level at…
