Question

When performing tests of significance (i.e., t-test and F-test) in regression analysis, one must assume that the disturbance term follows the ___________ probability distribution. (Points : 1)                                           chi-square
                                        Durbin-Watson
                                        Lagrangian
                                        normal
                                        none of the above
                                            
                         

                     18. Demand functions in the multiplicative form are most common for all of the following reasons except: (Points : 1)                                           elasticities are constant over a range of data
                                        ease of estimation
                                        exponents of parameters are the elasticities of those variables
                                        marginal impact of a unit change in an individual variable is constant
                                        c and d
                         

Explanation / Answer

17 = Normal

18 = marginal impact of a unit change in an individual variable is constant

19 = multiplicative

20 = 0.0

21 = true

22 = Maximize Shareholders Wealth
