Abstract.This paper introduces a family of recursively defined estimators
of the parameters of a diffusion process.
We use ideas of stochastic algorithms for the
construction of the estimators.
Asymptotic consistency of these estimators and asymptotic normality
of an appropriate normalization are proved. The results are applied to
two examples from the financial literature; viz., Cox-Ingersoll-Ross
model and the constant elasticity of variance (CEV) process illustrate
the use of the technique proposed herein.
