ii. For the linear model yi = Bo + Bix; + ci, i = 1, 2, ..., n a 99% prediction interval for y is wider than a 95% prediction interval for yk. iii. For a certain regression situation it is reported that SST = 25, SSR = 30, and SSE = -5. These calculations are correct since SST = SSR + SSE.2.7. a. Consider the model yi = B + ci, E(ci) =0, V(6;) = 02, Cov(ci, E;) = 0 for i * j, i = 1, 2, ..., n Find the LSEs of B and o 2. b. Discuss the following statements: i. For the linear model yi = Bo + Bixi + ci, i=1, 2, ..., n a 95% confidence interval for MK = Bo + Bixx is narrower than a 95% prediction interval for yk
