Dear Statalist,

I have estimated a model like this:

elec= -12.83927*ldisp + .7345735*ldisp2 + (other variables)

What I wanna do is to find the corresponding value of ldisp at a threshold level of elec, say elec=0.7 (this is not turning point). I could solve equation -12.83927*ldisp + .7345735*ldisp2 + average of all other variables=0.7 to find ldisp, but I would like to know whether any command in Stata can help.

Thank you in advance!
