What is the use of panel data?
Panel (data) analysis is a statistical method widely used in Social science, epidemiological, and econometric analysis of two-dimensional (usually cross-sectional and longitudinal) panel data. Data is usually collected over time with the same individuals, and regressions are run on both dimensions.

What is the difference between panel data and summary data?
Pooled data occurs when we have a « cross-sectional time series », but the observations for each cross-section do not necessarily refer to the same unit. Panel data refers to a sample of the same cross-sectional unit observed at multiple time points.
What is the difference between cross-sectional data and panel data?

What is the unit of analysis for panel data?
Panel data analysis refers to the statistical analysis of data sets consisting of multiple observations per sampling unit. This can be generated by aggregating time-series observations across various cross-sectional units, including countries, firms, or randomly sampled individuals or households.
What are the 4 components of a time series?
The four components are:
- Long-term trends, which describe long-term trends;
- Seasonal changes, representing seasonal changes;
- Cyclical fluctuations, which correspond to cyclical rather than seasonal changes;
- Irregular variation, which is another non-random source of sequence variation.
What is a time series model?
