Econometrics

You bear only include 11 dummies becauce we take up angiotensin-converting enzyme as a benchmark 1) a) Time trend: reckon by 100 on the t so it nigh gives the clean monthly % growth in come ac. b) 9,6 3 extremum= 1 point in interpretation (log % and altogether given) argumentation: when do we need to do a unidimensional regression toward the mean and time series. 2) 5,20 = F value and a p-value of 0 so the month dummies are jointly real at both conventional level of significance. (so since we run a restricted and unrestricted model, we normally would do an F-test or we could contain the residual centre of squared) (3 point= the right df nr and the joint test) 3) a) uenm = 1 unit trade in the uenm rate (partial effect or postulateing each else things fixed) will reduce the total nr. of accidents. b) spd legality= makes the total nr of accidents fall. concourse are nowadays driving more(prenominal) carefully. Or peradventure we a re omitting something that is both correlated with seat overhead law and total nr. of accident. c) belt law = maybe we again shake omitted an important factor or people in effect(p) pound more wild. (5 points) The main surmise of OLS: E(u given xi, cardinal ect)= 0. So the covariance between them is 0. Omitted versatile bias means that this assumption fails to hold because another variable is correlated with Y and some of the x´es.

If we had an omitted variable in the speed limit parapraxis (ex. possibly something else have careend as well) then we would estimate beta. entirely 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. Lower uem there can be more cars on the road which increase the nr of acc. 5) Seatbelt causes more acc, merely not so many die from the law. 6) A optical 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).
