Consider a regression model of monthly time series data where we model the price of petrol which is dependent on the Crude Oil price and Exchange rate (against US$). Data for the three variables were collected over a 50 month period. Suppose the estimation results showed that the Durbin-Watson (DW) test value d is 1.38. Perform the DW test for first order positive autocorrelation of the error terms at the 5% level of significance. Model: et = r...

Consider the following regression results of B for time series data. The dependent variable is the log of real consumption and the regressors are all lagged by one period. The coefficients are estimated by OLS method. *, **, and *** indicate that the coefficients are significant at the 10%, 5%, and 1% level, respectively. The F- test in the last row tests the joint hypothesis that all the coefficients except the constant are zero and their p-values are provided in...
