September 2009 15:55 An: statalist@hsphsun2.harvard.edu Betreff: st: Creating a variable taking the value of elasticity Dear Statalist, I have a simple dataset containing two variables, x and y. I regress ln(y) on ln(x) and observe the coefficient on x as elasticity. I then want to create a variable taking the value of this coefficient. How would I do this? Something like local elas=e(b); gen elas=`elas', except e(b) contains all the coefficients, and I just want one. A related question: when I regress y on x and then input "mfx, eyex," the ey/ex value is not the same as the coefficient I obtain using regress ln(y) ln(x). Why? Also: how would I extract the ey/ex value from the mfx output in order to create a variable taking that value?
