Hi all,
I have panel data spanning over two years (2003 and 2005) with 4862x2=9724 observations I would like to estimate a dynamic panel data model:
y c y(-1) a b c d
my instrument list is: @dyn(y,-2) a b c d
So, with the example from the help file by my side, I opened up the Dynamic Panel Data wizard and started entering in values that are as close to the example as possible, except using my variables as described above. After completing the wizard I clicked estimate and I got the error "Not Enough Observations" - this is pretty confusing to me as the example I was following only has 611 observations, so Im not really sure why im getting a complaint but the example didnt....
Cheers and Thanks,
Andrew.

Re: Dynamic Panel Data Estimation
hi guys,
How do you calculate minimum observation needed to undertake arellano bond GMM estimation (two step). The reason why i ask is because i am receiving message "number of instruments greater than number of observations" when i try to estimate using dynamic panel wizard. I have attached the workfile in which i fail to calcualte AB- 2 step dynamic panel data model.
Just wanted to be sure about 2 thing ?
1) Is it indeed lack of the observations cross section i presume) because of which i cannot perform dynamic panel estimation
2) How many cross section i need (some way to measure or a rough gauge) input to be able to perfrom dynamic panel estimattions
Thanks for your help!
