I have an unbalanced panel data set (countries and years). For simplicity let's say I have one variable, x, that I am measuring. The panel data sorted first by country (a 3-digit numeric country-code) and then by year. I would like to write a .do file that generates a new variable, z_x, containing the standardized values of the variable x.Pengertian Data Panel. Data panel sering disebut juga sebagai data longitudinal. Data ini melihat observasi beberapa variabel cross section dan memperhatikan data deret waktu yang digunakan (time series).

now I see the issue. If you run the Stata code I provided you with in my previous post, the F-test automatically reported as a footnote in result table tells you that -xtreg, fe- is actually better than pooled -ols-. For -hausman- specification test, expanding on the previous Stata code, you may want to try: Code:
