{title:Description}

{pstd}
{cmd:eivreg} fits errors-in-variables regression models.


{title:Options}

{dlgtab:Model}

{phang}
{cmd:reliab(}{it:indepvar # }[{it:indepvar # }[...]]{cmd:)}
specifies the measurement reliability for each independent variable
measured with error.  
Reliabilities are specified as pairs consisting of an independent
variable name (a name that appears in {it:indepvars})
and the corresponding reliability r, 0 < r {ul:<} 1.
Independent variables for
which no reliability is specified are assumed to have reliability 1.
If the option is not specified, all variables are assumed to have reliability
1, and the result is thus the same as that produced by {helpb regress}
(the ordinary least-squares results).

{dlgtab:Reporting}

{phang}
{opt level(#)}; see {help estimation options}.
