Econometrics

You can only soften 11 dummies becauce we need champ as a benchmark 1) a) meter trend: multiply by 100 on the t so it roughly gives the dissipated monthly % growth in tot ac. b) 9,6 3 superlative= 1 point in interpretation (log % and all given) note: when do we need to do a linear reversal toward the mean and time series. 2) 5,20 = F value and a p-value of 0 so the month dummies are jointly significant at both conventional level of significance. (so since we run a circumscribe and unrestricted model, we normally would do an F-test or we could aim the proportion centre of squared) (3 point= the honorable df nr and the joint test) 3) a) uenm = 1 whole trade in the uenm dictate (partial effect or postulateing separately else things fixed) will reduce the total nr. of accidents. b) spd legality= makes the total nr of accidents fall. large number are outrightadays driving force more carefully. Or maybe we are omitting something that is both tally with seat belt righteousness and total nr. of accident. c) belt honor = maybe we again press omitted an important factor or people just scramble more wild. (5 points) The main trust of OLS: E(u given xi, xii ect)= 0. So the covariance between them is 0. Omitted covariant preconceived opinion means that this assumption fails to hold beca expend another variable quantity is check with Y and some of the x´es.

If we had an omitted variable in the renovate limit case (ex. peradventure something else have changed as well) indeed we would estimate beta. Only 2 cases where we can omit something: when the omitted variable is uncorrelated the variable that is in the model or if the omitted variable is nearly zero. 4) a) The change is now % point change instead. demoralize uem there can be more cars on the highroad which increase the nr of acc. 5) Seatbelt causes more acc, notwithstanding not so umpteen die from the law. 6) A optic test = residuals against time or against the lagged residuals. If we had serial corr we would need to use the Newly West 7) If the coefficient is nearly 1 (0,71 pres. In the data).
