WebC ( u) = ∫ d z e i u z f ( z) = 1 1 + t 2 u 2. This is clearly not a Gaussian as we expect from a Brownian motion. Regarding the scaled random variables I think you have to look at the limit in distribution. The pdf of Z t = B t / t is. g ( z) = t 2 π t e − 1 2 ( z t) 2 t. which goes to zero uniformly as t → ∞.

Web31 de mai. de 2024 · Since W ( s) and W ( t) are not independent, the variances cannot just be added to conclude it has variance s + t. To find the actual distribution of W ( s) + W ( t), note that W ( t) can be written as the sum of independent increments of the Brownian motion: W ( t) = [ W ( t) − W ( s)] + W ( s) W ( t) + W ( s) = [ W ( t) − W ( s)] + 2 ⋅ ... Web2 de mai. de 2024 · The idea in solving this problem is to represent the sum B ( s) + B ( t) as the sum of an increment. That is, B ( s) + B ( t) = 2 B ( s) + B ( t) − B ( s) and since we know incrememnts of a brownian motion are independent, then 2 B ( s) is independent of B ( t) − B ( s). Thus, we can easily get that E [ B ( s) + B ( t)] = 0 & V a r [ B ( s ...
