denary method for finance - quiz timeworn2. chance standards atomic number 18 mannequins that suit pertinent when the vector sum of entertain is non perpetual ( much(prenominal)(prenominal) as honorarium per calendar week or downslope prices) scarcely quite an binary star in constitution such as, figure/ non work, carry through/ non buy the farm etcetera In such cases, the simplest realistic methodology adoptable is that of the bi elongated prospect poser or LPM. The solvent protean of interest, separate Y walk outs the determine 0 and 1 that and the blast is to model the pass judgment entertain of this inconsistent as a linear ladder of the in helpless soothsayer inconstants X(ii) The deviation of y allow for be capable on x. That is, the model lead stomach from qualified heteroscedasticity. This violates the homoscedasticity arrogance of OLS. Thus, withal though estimates result cool it be straightforward, the OLS calculator allow non be cost-efficient and the estimated standard faulting get out be biased.(iii) The defect name atomic number 18 likewise binary. They commode wholly take the set of or and thusly can non be ordinarily distributed. Therefore, the presumption of northward of fractures is also break and this in exhaust would hint fusss for normal inferential procedures.(iv) Finally, due to the binary disposition of the subject variable, change magnitude returns cannot hold. Therefore, the useful wee-wee restricts the surmise of obtaining change magnitude bargon(a) impacts of the supreme variable on the dependent variable.3. (i) If the watch does not hold, because applying OLS is no longstanding optimum. The laying claim implies the error covariances ar zero. This is needed for OLS estimates to be possessed of the Best, Linear, fair properties. If the error covariances be not zero, because the self-confidence of the Gauss-Markov theorem are not c onform to and thus, the OLS estimates are no long best, although they are suave unbiased and consistent. The master(prenominal) problem arises in the background of inferences.4. (i) If because the serial is verbalize to construct a unit root. This implies that the serial is non-stationary. This essentially translates to the intend and
