Using standard models to estimate panel data

Panel data models are one of the important standard models in the field of economic sciences. Because of its special importance in increasing the number of observations, which allows to reach more reliable standard results; In addition to the absence or decline of many econometric problems, similar to the problem of the instability of the variance of random error, and accordingly this topic has been divided into three axes; The first axis included the theoretical framework of the longitudinal data model (Panel data), while the second axis measured the relationship between economic growth and the production of electricity from nuclear energy; While the third axis came to analyze the impact of nuclear energy consumption on the environment, and then finally the application to Egypt.
