{title:Description}

{pstd}
{cmd:svy: ivreg} fits instrumental variables regression for complex survey
data; see {helpb ivreg} for a description of this model involving nonsurvey
data, help {helpb "svy: regress"} for linear regression for survey data.

{pstd}
Specifically, {cmd:svy: ivreg} fits a linear regression model using
instrumental variables (i.e., two-stage least squares) of {it:depvar} on
{it:varlist1} and {it:varlist2} using {it:varlist_iv} (along with
{it:varlist1}) as instruments for {it:varlist2}.

{pstd}
In the language of two-stage least squares, {it:varlist1} and {it:varlist_iv}
are the exogenous variables and {it:varlist2} the endogenous variables.
