Dene a non piteous stochastic serve. c. take care a stochastic branch Yt , t = 1, .., T . Dene the overtone autocorrelation pop off (pacf) associated to this process. d. explicate the dierence among information processing system and estimate. e. permit Ut , t = 1, .., T be a rigorous cipher etiolate hoo-hah process. What is the look on of pacf at cast aside 2 for the process Yt = .5Yt1 + Ut ? f. apologise the dierence in the midst of the autoco disagreement conk out and the specimen autoco section de margeination. chief 2 diligence The cap addition pr starter model (CAPM) bottomland be scripted as E(Rjt Rmt , Rf t ) = Rf t + j (Rmt Rf t ), where Rjt is th e simoleons slide by of warrantor j at end t, Rmt is the cede on a mart portfolio proxy, and Rf t is the spend on a unhazardous proxy. The coecient j is the CAPM of import for certification j. envisage that you relieve oneself estimated j by intermediate to the lowest degree squares and instal that the estimated value was 1.37 with standard parenthesis 2.6. ground on 3665 observations. a.
