Estimating TSLS equation in panel.

Postby Yokogil » Thu Aug 30, 2012 3:00 pm

Hello I'm estimating a TSLS equation model in a panel.

I have 4 variables:
a) LPI
b) GDP
c) XMGDP
d) DENSITY

And my instrument used is:
a) YEARSONCHAIR

How can i write the code to program the equation? It keeps saying that I need more instruments.

Non-normality and collinearity are NOT problems!

You need at least as many instruments as right hand side variables.
