st: New -hte- package available from SSC
Date
Thu, 25 Feb 2010 06:28:28 -0500
A new package called -hte-, authored by Ben Jann, Jennie E. Brand, and
Yu Xie, is available from the SSC Archive. In Stata type
. ssc install hte
to install the package.
-hte- is a command to perform heterogeneous treatment effect analysis.
It uses -pscore- by Becker and Ichino (2002) to construct balanced
propensity score strata and, within each stratum, estimates the average
treatment effect. -hte- then tests for linear trend in treatment effects
using variance-weighted least squares. The stratum-specific treatment
effects and the estimated linear trend are displayed in a twoway graph.
Note that the -pscore- command is required, which is available from the
Stata Journal website (type -net sj 5-3 st0026_2- in Stata).
An application of this methodology appears in Brand and Xie (2010).
