Thank you Nick, I will take into account your suggestions about spatial dependency. May be the spatial econometric approach would be a good choice for these kinds of regression.The endogenous variables problems would also render the consistent and robust of related parameters. the NL2SLS methods would be a good choice. My project has a long way to go!
