For example, I find a lot of people using xtreg d.y d.x1 d.x2 to run the first difference panel regression.
However, if there is a command using xtreg y x (some code defining first difference) to run the first difference panel regression.
What if I don't want the d. and gen d.variable to defien first difference, is there any other way.
