Pooled regression and dummy variables

[Kev Summersgill]

I'm a bit of a novice with excel. I have a dataset of
national ststistics which only has a few years so I can't
run a time series regression with any confidence. Also
there aren't enough categories to run a cross-sectional
analysis with any confidence. This is the only dataset
available for what I need and have been advised that a
pooled regression (time series cross sectional
regression) using dummy variables is the best way - I
don't know how to do this on excel though.

Thanks for any help
