You are required to answer one of the 2 question sets. Each question set has a major element (on either rail demand (time series analysis) or rail cost (panel data analysis)) and a minor element (on rail cost or rail demand respectively). Please provide Eviews output for the tasks below and comment briefly (maximum 1500 words in total). For the minor element of each question set (the last question in the set), you do not need to undertake any econometric analysis using real data.
