Hi, everyone.
I posted some stuff to the course web site:
1) the (correct) solution set to PS7
2) the new PS8, due next week in section
I have some hints for you for PS8:
* You can use Zelig for this problem set and your life will be much
easier if you do. See demo(match) for an example.
* Write a function to calculate the ATE and ATT given certain
generalized inputs, such as the formula, model, data, and treatment
indicator. You should use zelig(), setx() and sim() in this high-level
function. This will make your week much easier.
* Per the discussion we had in section, I gave very specific definitions
for the treatment and control groups. Please follow these definitions
even if you disagree with the reasoning.
Finally, the problem set looks long, but that's because most of the
answers this week will be numeric rather than graphical and I can't check
numbers outside of tables, so I have provided the tables for you to fill
in. Please use the same row and column layout in your solution sets!
If you have any questions, please let me know. Thanks!
Olivia.
