In the Angrist, Mastering metrices book (page 118, chapter 3, Instrumental variable) Angrist calculated "recidivism was greater among suspects assigned to be coddled than among those assigned to be arrested."
I am having very hard time how they come up with those number.i think the first term E[Y_i\z_i=1]=(#person get aressted)/(#Given their Assigned Treatment was coddled/Not arrested)=(19+26)/(108+104). However i can't find hoe they calculated the second term =.097
This is my first post to the forum and i am trying to learn econometrics as a self study. if anyone could help in this regard i will highly appreciate that. Thanks
