Using eviews to process panel data, how to add virtual variables? Satisfaction points. I have the data of all provinces in China, which should be analyzed by the eastern and central and western regions. Adding dummy variables in EVIEWS means adding a column of variable data in the data table, with positive data taking 1 and negative data taking 0. For example, to investigate the impact of investment in the eastern and central and western regions on economic growth, we set a regional dummy variable, which is 1 in the eastern region and 0 in the central and western regions, and put it into EVIEWS for processing together with GDP and investment variables. If the dummy variable is positive and significant, it shows that the eastern region has obvious promotion effect on economic growth due to the influence of regional characteristics.
