Statistical Software Packages
Synthetic Control Method
is a statistical software package for R,
Stata, and MATLAB that implements synthetic
control methods for causal inference in
comparative case studies as described in Abadie
and Gardeazabal (2003), Abadie,
Diamond, and Hainmueller(2010), and Abadie,
Diamond, and Hainmueller (2011).
ebal is a statistical
software package for R and Stata that
implements entropy balancing for causal
effects as described in Hainmueller (2011).
Regularized Least Squares
is a statistical software package for R
that implements Kernel
Regularized Least Squares (KRLS) as described in Hainmueller
and Hazlett (2012).
method is designed to flexibly fit response
surfaces of the form y=f(x) as they arise in
regression and classification problems without
relying on linearity, additivity, or other assumptions
that use the columns of the predictor matrix
X directly as basis functions.
