Document Content and Description Below

Which of the following is one of the assumptions of regression? • Question 2 1 out of 1 points Which of the following is one of the assumptions of regression? • Question 3 1 out of 1 points In a multiple regression model, the distribution of error is assumed to be • Question 4 1 out of 1 points The Durbin Watson statistic is used to measure • Question 5 1 out of 1 points If the residuals in each period are correlated with the residuals in one period before, there exists • Question 6 0 out of 1 points A test that is used to find out whether the errors are independent of each other is called • Question 7 1 out of 1 points When two or more independent variables are related linearly, there exists • Question 8 1 out of 1 points A parsimoneous model • Question 9 0 out of 1 points In testing a hypothesis about one of the regression coefficeients a higher value of the test statistic • Question 10 0 out of 1 points In a regression problem, if the coefficient of one of the independent variables is positive while we expect it to be negative, then there may exist • Question 11 0 out of 1 points When multicollinearity exists in a regression problem, the model • Question 12 1 out of 1 points Which of the following statistics can only vary between 0 and 4? • Question 13 0 out of 1 points The stepwise regression • Question 14 0 out of 1 points Which of the following procedures is not available in StatTools, • Question 15 0 out of 1 points StatTools may be used to calculate • Question 16 0 out of 1 points When an outlier is observed in regression analysis, • Question 17 0 out of 1 points The easiest way to find out whether there are any violations of the regression assumptions is to • Question 18 0 out of 1 points When we observe a fan-shape in a scatterplot, • Question 19 0 out of 1 points When the distribution of error for given values of the independent variables is normal, • Question 20 0 out of 1 points When nonconstant variance is present, it can be remedied by • Question 21 0 out of 1 points The Chi-Square method can be used to detect the violation of which assumption? • Question 22 0 out of 1 points The Se may be used to estimate • Question 23 0 out of 1 points Durbin-Watson statistic measures the autocorrelation between • Question 24 1 out of 1 points The standard error of prediction for an individual value of the response variable • Question 25 0 out of 1 points Consider the model Pred_Y = -2,000 + 700LnX. • Question 26 1 out of 1 points Forward procedure, • Question 27 0 out of 1 points The backward elimination procedure is a(n) • Question 28 1 out of 1 points Multicollinearity often causes the regression coefficients • Question 29 0 out of 1 points In multiple regression, the correlation among independent variables is called • Question 30 0 out of 1 points In time series data,
