How could I plot coefficients from all the regressions below into a same graph? There is one regression for each year and I would like to have coefficients on the yaxis and years on the xaxis.
:
foreach i in 2007 2008 2009 2010 2011 2012 {
areg ppc d_sem i.mes [w=npar] if ano==`i', absorb(mun_res) vce(cluster mun_res)
outreg2 using "reg_conv_ano.xls", append ctitle (TPC `i')
}
