What happens if an irrelevant x is included in the regression model? correct answers As estimators (betas) are unbiased, the estimate of the coefficient will generally be around 0. This inclusion has an undesirable effect on the variance of the other estimators. What happens if a relevant variable is omitted? correct answers The estimators (betas) will be biased (over or under-estimated). Omitted variable bias! What is the difference between the Breusch-Pagan test and the White-test? cor...
