ipt: a Python 3.7 package for causal inference by inverse probability tilting ----------------------------------------------------------------------------- by Bryan S. Graham, UC - Berkeley, e-mail: bgraham@econ.berkeley.edu This package includes a Python 3.6 implementation of the Average Treatment Effect of the Treated (ATT) estimator introduced in Graham, Pinto and Egel (2016). The function att() allows for sampling weights as well as "clustered standard errors", but these features have not yet been extensively tested. The package also includes a particular implementation of the E-estimator for the partially linear regression model due to Newey (1990) and Robins, Mark and Newey (1992). An implementation of the Average Treatment Effect (ATE) estimator introduced in Graham, Pinto and Egel (2012) is planned for a future update (as well as other causal inference estimation procedures). This package is offered "as is", without warranty, implicit or otherwise. While I would appreciate bug reports, suggestions for improvements and so on, I am unable to provide any meaningful user-support.
