Instrumental Variables 

At 17:00 in the video and the first line of slide 9 should be Durbin-Wu-Hausman test for endogenous (not exogenous) regressors.

this is genius. For first time i understood teacher clearly explaining IV from basics, which is super needed as this is what i was missing in every class i ever attended on this. Very well presented!!

One of the best intro to IV videos I've seen.
