Let y: be a natural logarithm of steak price observed at some consecutive days t = 1,1 ...11. The analyst estimates a rnedel as air: = 2.5 + (1.53.54. Given J'mn = 2 she can forecast the stock price at t = 101 to he: 0.3.103 013.99 Or. 2. @111 OE. 1. An estimated regression equation is y = -1 + 2In (x). Then we can forecast: O a. = 2.72 if x = -1. O b. y =1if x =1. Oc x =1ify =-1. O d. y = 0.05 if x = -1. O e. y =-1if x = 1
