Hi Gareth, thank you very much for your help. This link seems good to me. Now, I know what I should choose for my essay. However, I still have some queries as follows:

- How can we know our data comply with fixed or random effects, cross section fixed effect, weighed or unweighted. Which test should be done to clarify it.
- If we use panel workfile, how can we determine whether time effects to our variables. I mean that, if we only have two years (exp: 2005 and 2006) , it will be easy to use dummy variable (such as dummy = 1 if year = 2005; dummy =0 if year = 2006). Unfortunately, if we have many years (for example year 2005 to 2009). How can we define for dummy variable in this case?

Thank you very much for you sharing and instruction.
