Consider the following model:yi=α+βxi+i;i= 1,2,···,n(4)wherexiis fixed in repeated sampling, and the random disturbance termisatisfies the usualassumptions ofE(i) = 0V(i) =σ2∀iE(ij) = 0∀i6=j(5)Let ˆi, ˆαandˆβdenote the OLS residuals and the parameter estimators, respectively. The re-gression model of (4) is fitted to the data: (x1,y1),···, (xn,yn), giving least squares estimates ˆα1 andˆβ. Given a new valuexn+1for the […]

a.Draw the decision tree for this decision. The tree should show the various nodes and branches, together with relevant payouts and probabilities. You may produce the tree using any medium (Excel, by-hand, PowerPoint etc.). If you use Excel, submit the file. If you use another medium, produce a clear image (e.g. a screenshot or photograph) […]
