Panel data is obtained through a longitudinal study, when the same entities (e.g. individuals, companies, countries) are observed in time. Thus, the panel dataset consists of both time series and cross-sectional data. It has extensive use in biological and social sciences. There are considerable advantages of using panel data as opposed to using only time series or only cross-sectional data. The additional information that the panel data provides allows for more accurate estimations. The panel data estimation methods require less assumptions and are often less problematic than simpler methods.
