Panel Data Variance Decomposition

[caveman529]

I hope to use statistical procedure to partition a variable of a panel dataset into cross-sectional variation and time-series variation.  Suppose my data looks like:

Y              X             ID            DATE

I hope to know how Y varies cross-sectionally according to ID holding DATE fixed.  I also hope to know how Y varies according to DATE time-series, holding ID fixed.  My description may not conform to statistical lingo, could you offer me some advice on how to do so?  Thank you –

Strongly recommend you cross past this to the Econometrics and Forcasting forum. and @eta_kps will almost certainly be able to give some guidance in this area.
