...well as dimension of a model (additional between equations). So to begin with, I try to estimate pool, which is obviously easier, and proceed as follows:
Consider the following specification:
model.3eq.33 <- specify.model( )
ln.inv.p0.pc -> ln.grp.phvi.pc , beta13 , NA
ln.migr.new -> ln.grp.phvi.pc , beta12 , NA
ln.grp.corr.pc97 -> ln.grp.phvi.pc , gamma11 , NA
ln.sh.ind.rawwid...
