Panel and Pooled Data and Implementation in EViews

Panel Data and Pooled Data are two highly powerful econometric structures that simultaneously combine both time-series and cross-sectional dimensions. Panel Data is optimally designed for large samples containing hundreds or thousands of cross-sectional units stacked together into a single series. Conversely, Pooled Data is ideal for datasets featuring a relatively small number of cross-sectional units (such as the G7 countries), where variables are strictly managed as individual series appended with unique identifiers. Both methodologies significantly increase the degrees of freedom, reduce multicollinearity, and effectively control for unobserved heterogeneity among units. To implement Panel analysis in the EViews software, you must first structure your workfile into a Panel format (selecting either Dated Panel or Undated Panel) by explicitly specifying a spatial identifier (Cross-section ID series) and a time variable (Date series). The equation estimation process is seamlessly executed via the Quick - Estimate Equation... menu. On the Panel Options tab, users can readily configure Fixed Effects or Random Effects models, and apply robust GLS weighting techniques to correct for heteroskedasticity. For Pooled Data, the workflow initiates by creating a Pool object via Object -New Object... - Pool and manually entering a list of cross-section identifiers (for instance, CAN, UK, US). Variables are dynamically referenced using the ? wildcard character (e.g., GDP?). By clicking the Estimate button directly within the Pool object window, you can flexibly specify common coefficients applied across the entire pooled sample (Common coefficients) or highly customized coefficients that vary by individual unit (Cross-section specific coefficients), delivering maximum analytical flexibility.
