Question 2 Let W(t) be a standard one dimensional Brownian motion and let Q(t) be the Brownian Bridge on [0, 1], i.e. Q(t) = w(t)tW(1), tɛ [0,1]. 2.1 Show that Q(t) is a Gaussian process with EQ(t)=0, E(Q(t)Q(s)) = min(t, s) — ts. 2.2 Now consider the stochastic process Y(t) = Бакже which is related to the area under the Brownian bridge curve. Show that ts² $3 (ts)2 E (Y(t)Y(s)) = 2 - s
