I've to make a presentation on research methods that happens to include endogenous and instrumental variable. Now, they are not seeming very similar to me, but still I'm failing to draw a clear line and afraid of confusing the two. Can someone kindly explain the differences and similiraries...
I am aware that Stata 14 has a user written package called -punaf- to calculate Potential attributable fractions (PAF) as a post regresion procedure. Is there any way to calculate PIF. I couldnt find any clue from my search.
Thanks for sharing your insight.
