%description
Estimation and inference for coefficients of linear EIV models with
symmetric measurement errors. The measurement errors can be homoscedastic
or heteroscedastic, for the latter, replication for at least some
observations needs to be available. The estimation method and asymptotic
inference are based on a generalised method of moments framework, where
the estimating equations are formed from (1) minimising the distance
between the empirical phase function (normalised characteristic function)
of the response and that of the linear combination of all the covariates
at the estimates, and (2) minimising a corrected least-square discrepancy
function. Specifically, for a linear EIV model with p error-prone and q
error-free covariates, if replicates are available, the GMM approach is
based on a 2(p+q) estimating equations if some replicates are available
and based on p+2q estimating equations if no replicate is available. The
details of the method are described in Nghiem and Potgieter (2020)
<doi:10.1093/biomet/asaa025> and Nghiem and Potgieter (2025)
<doi:10.5705/ss.202022.0331>.
