st: three dimensional panel

[Prashanth Mahagaonkar <mahagaonkar@econ.mpg.de>]

hi all
I have a dataset with country,sector and year dimensions(i,j,t structure).
One of my independent variables varies in country and year, while my 
dependent variables vary with all the three.
There must be some way to analyse such data, but I am unaware of it.
Can anyone help me?
