USEFUL STATA COMMANDS: coefplot
By Andre Lee (Georgetown MIDP 18)
The coefplot command allows you to plot results from estimation commands. It is a user package, so you will have to find and install it by inputting into the Stata command line:
Click on the coefplot install link.
Now, using the auto database, I made a simple regression and store it in memory as model_1:
sysuse auto regress price gear_ratio mpg rep78 turn weight trunk estimates store model_1
model_1’s coefficients can now be plotted with:
coefplot model_1, drop(_cons) xline(0)
I can also graphically compare the coefficients and confidence intervals for each independent variable used in the models:
regress price gear_ratio mpg rep78 turn weight headroom estimates store model_2 coefplot model_1 model_2, drop(_cons) xline(0)
I can also separate the predictor variables into individual graphs:
coefplot model_1 || model_2, yline(0) bycoefs vertical byopts(yrescale) ylabel(, labsize(vsmall))

The information was sifted from his various article on useful Stata commands and adapted for sysuse auto (native database in Stata) for the reader’s ease of use.
