A. Satorra et H. Neudecker, ON THE ASYMPTOTIC OPTIMALITY OF ALTERNATIVE MINIMUM-DISTANCE ESTIMATORS IN LINEAR LATENT-VARIABLE MODELS, Econometric theory, 10(5), 1994, pp. 867-883
In the context of linear latent-variable models, and a general type of
distribution of the data, the asymptotic optimality of a subvector of
minimum-distance estimators whose weight matrix uses only second-orde
r moments is investigated. The asymptotic optimality extends to the wh
ole vector of parameter estimators, if additional restrictions on the
third-order moments of the variables are imposed. Results related to t
he optimality of normal (pseudo) maximum likelihood methods are also e
ncompassed. The results derived concern a wide class of latent-variabl
e models and estimation methods used routinely in software for the ana
lysis of latent-variable models such as LISREL, EQS, and CALIS. The ge
neral results are specialized to the context of multivariate regressio
n and simultaneous equations with errors in variables.
