**Abstract.**
In this paper we investigate some aspects like
estimation and hypothesis testing in the simple structural regression
model with measurement errors. Use is made of orthogonal
parametrizations obtained in the literature. Emphasis is placed on
some properties of the maximum likelihood estimators and also on the
distribution of the likelihood ratio statistics.

*Key words and phrases*:
Bartlett correction factors,
information matrix, likelihood ratio statistics, maximum likelihood
estimator, orthogonal parametrization, structural normal model.
