Panel data analysis

Classical finance has undergone a major change in recent years. In our modern world, where risk becomes more complex and difficult to calculate, more sophisticated mathematical techniques and products are needed to quantify such new risks. The financial sector should have a solid structure in order for the real sector to be able to supply the financing it needs without interruption. Financial sector wants to maintain and increase their profitability in a sustainable manner as they do in other production companies. The functioning and change of the financial system structure have always been interesting for researchers from the past to the present. Researchers investigating the financial system try to test financial data using econometric methods. Financial econometrics is the application of statistical methods to financial sector data. Panel data, which is composite data, accommodates both the horizontal and the time dimensions of the data. Therefore, researchers who want to examine the change of a group (each observation value in horizontal section) over time with econometric tests frequently need panel data analysis. By using panel data methods, more reliable and healthy results can be achieved.
