I wonder if someone could provide an explanation of the meaning of
"under the assumption that everything stays the same except that the
treatment indicator is switched to ti = 0"
Hi,
I'd like to know when this feature will be back,
"Average Treatment Effect" quantities of interest are not being included
in
zelig models temporarily. Simulation of these qi's will return pending a
minor update to the 'setx' function.
kindly respond to private email - not on the list
thanks marwan
