[Slides 139-153] and Linear Model Exercise 18 a)b)c)e). The problem with using the Normal distribution for beta-hat_j: the unknown variance sigma^2 of the random errors. Estimating sigma^2 with the Residual Means Square (QMRE) and its effect on the pivot quantity for inference on the model parameters beta_j. Confidence intervals for individual beta_j. Hypothesis tests for individual beta_j. An example: Exercise 18 (videiras dataset).
