Suppose that xo, ¤1,..., Xt, Xt+1, ..., denote the (daily) share prices of a particular stock over time. Answer the following questions (you should add a bias term): ••• ) 1. Write a linear model to predict xt+1 using the share prices on the two preceeding days, i.e., xt and Xt-1• 2. The more useful quantity to predict is At+1:= xt+1 – Xt (the :=' means 'is defined to be'), the change in share value. Write a linear model to predict At+1 using xt and - Xt-1•
