I have a data set , 12 countries and a period of 10 years
which of them have different year period, like country A data from year 1-10, B data from year 2-10, and 4-10
and none of them have data like this: year 1, missing 2,3, year4-10
so my data is called unbalanced data right?
and i can use all the command : xtreg fe, xtreg re,xtreg fe robust, xtreg re robust, xtserial, collin, hausman, hausman sigmamore, xttest3, xttest0,...
for my unbalanced data, right?
