{pstd}{hi:hte} {hline 2} Heterogeneous Treatment Effect Analysis


{title:Syntax}

{pstd}
    Stratification-Multilevel Method (SM):

{p 8 15 2}
    {helpb hte sm} {it:...}

{pstd}
    Matching-Smoothing Method (MS):

{p 8 15 2}
    {helpb hte ms} {it:...}

{pstd}
    Smoothing-Differencing Method (SD):

{p 8 15 2}
    {helpb hte sd} {it:...}


{title:Description}

{pstd}
    {cmd:hte} performs heterogeneous treatment effect analyses as proposed by
    Xie, Brand, and Jann (2012). Three methods are supported, the 
    stratification-multilevel method (see help {helpb hte sm}), the 
    matching-smoothing method (see help {helpb hte ms}), and the
    smoothing-differencing method (see help {helpb hte sd}).


{title:Dependencies}

{pstd}
    {helpb hte sm} requires {cmd:pscore} (Becker and Ichino 2002) and 
    {helpb hte ms} requires {cmd:psmatch2} (Leuven and Sianesi 2003). To 
    install these programs on your system, type:
    
        . {stata "net install st0026_2, from(http://www.stata-journal.com/software/sj5-3)"}
        . {stata "ssc install psmatch2"}
