Does anyone know a clever way to add R2 to "graph twoway lfit"?

[Michael Andersonnnn]

I am using the below code to fit a linear regression line, Private_Hospital is a binary variable

graph twoway lfit Private_Hospital_1 Differential_Distance

I would like to show the R2 on the graph if possible, does anyone know how to do this?

i have looked at the help file and no luck so far

See the option -text()- in the documentation to insert it within the plot region.

sysuse auto, clear
set scheme s1mono
qui reg mpg weight
tw (scatter mpg weight) (lfit mpg weight), leg(off) title("R{sup:2}= `=string(`e(r2)', "%3.2f")'")

Thank you so much, do you know how I can make the R2 to three decimal places?

[Andrew Musau]

Change "%3.2f" to "%4.3f". See
