Multi-Model `coefplot` (LaTeX)

Using tenuredata.dta, compare the fertilizer and labor coefficients across multiple specifications.

Run and store three regressions, all with vce(cluster panelid):
- m1: yield on q_f_ha lt_f_ha i.irrig i.tenure
- m2: yield on q_f_ha lt_f_ha i.irrig i.tenure i.site
- m3: yield on q_f_ha lt_f_ha i.irrig i.tenure i.site i.year

Create a multi-model coefplot showing only q_f_ha and lt_f_ha:

 coefplot    (m1, label("Baseline") ) ///
             (m2, label("+ Tenure/Irrig") ) ///
             (m3, label("+ Village/Year FE") ), ///
                keep(q_f_ha lt_f_ha) xline(0) ///
                xtitle("Coefficient size")

Export the graph: graph export "$answ/10-coefplot-multi.png", replace
In your lastname.tex, include the graph using \includegraphics[width=0.8\textwidth]{10-coefplot-multi.png}
