ABSTRACT
Consider a sequence of observations with a distribution depending on
and
, where
is a vector to be estimated and
a nuisance parameter. A general approach to estimating
is the method of estimating equations for which an estimator of
is a solution of an equation consisting of
and the first
observations. In this paper, we study some asymptotic properties of such
an estimator under a very general setting. Sufficient conditions are given
for the consistency and asymptotic normality of an estimator of
from any estimating equation without a dimensionality assumption on the
nuisance parameter. The theory is illustrated by several examples.
