multi-site randomized experiments with few units per site.

{title:Description}

{p 4 8}
{cmd:multisite} wraps in three commands to estimate treatment-effect heterogeneity across sites in multi-site RCTs, and more generally in stratified RCTs. The three commands wrapped by {cmd:multisite} respectively estimate the variance of ITTs across sites, the variance of LATEs across sites, and regressions of ITTs on explanatory variables.

{p 4 8}
{cmd:multisite_varITT} computes the estimated variance of ITTs across sites in multi-site randomized trials.

{p 12 12}
{help multisite_varITT}. 
{p_end}

{p 4 8}
{cmd:multisite_varLATE} computes the estimated variance of LATEs across sites in multi-site randomized trials.

{p 12 12}
{help multisite_varLATE}. 
{p_end}

{p 4 8}
{cmd:multisite_regITT} computes the coefficients from a regression of site-level ITTs on site-level characteristics in multi-site randomized trials.

{p 12 12}
{help multisite_regITT}.
