[Gretl-users] IV Panel Estimation

Dear Gretl friends, I've been working to get familiar with a macro panel I'm doing - it comprises a number of variables of US States since 1992 until 2009. However, as everything in econometrics, I have to be very careful with some endogeneity issues. For this reason, I've working on finding suitable IV's for my estimations. However, I have some questions regarding Gretl's panel toolkit. The first is about the Panel IV GUI and how it relates to the tsls function. I am pretty sure it is improper, yet I will ask nonetheless -- is it still feasible to use tsls for the panel estimation? I am pretty sure you can't, since it doesn't demean the data and the like, but I want to be sure since I am more familiar with the test outputs reported there. If not, how can you script what Allin programmed in the Panel IV GUI? I've not been able to find the script functions for what it is done there (I see there is an ivpanel function in the GUI example but nothing else is said about it). Is it equivalent to using a dpanel with instruments? Thanks everyone! EF
