The federal government carries out a careful randomized control trial of 2,500 families with a new kid. Of these 1,000 are selected at random to the literature program and the other 1,500 do not. Of the 1,000 households assigned to receive the program, only 800 actually did. The control households were not treated. How would you calculate and interpret the intention-to-treat (ITT)? Is this the best measure to test whether or not the program is a success?
