现在特流行用图去展示回归系数和置信区间，感觉政治科学尤甚。

大多图都是R里面画的，Stata的有无相关命令？

【方法】

coefplot

coefplot -- Plotting regression coefficients and other results

regress price mpg headroom trunk length turn if foreign==0

estimates store domestic

regress price mpg headroom trunk length turn if foreign==1

estimates store foreign

coefplot domestic foreign, drop(_cons) xline(0)
