[R] Panel data

[Stefan Grosse]

Panel data is that you have e.g. several subjects 
(=individuals,firms,households) being tracked over a certain time (meaning 
there are repeated observations). One could roughly say that it is a 
collection of (quite similiar) time series. This makes the analysis better 
than pooling the whole set but it needs certain econometric tools. 

An example would be estimating wage elasticities.

Time series analysis usually just involves one subject (interest rates, share 
prices etc.) over some time.

Standard books on panel data analysis are also Baltagi: econometric analysis 
of panel data and Wooldridge: econometric analysis of cross sectional and 
panel data. Both are not introductionary texts since you do not know the 
difference between time series and panel data maybe you should start with an 
introductionary econometrics book like Wooldridge introductory econometrics 
or Verbeek: modern econometrics.

 said panel data is data on "same subject being tracked over time". But time
 series data also do the same. Please correct me if I am wrong. MD >
