We use Stein characterisations to derive new moment-type estimators for the
parameters of several multivariate distributions in the i.i.d. case; we also
derive the asymptotic properties of these estimators. Our examples include the
multivariate truncated normal distribution and several spherical distributions.
The estimators are explicit and therefore provide an interesting alternative to
the maximum-likelihood estimator. The quality of these estimators is assessed
through competitive simulation studies in which we compare their behaviour to
the performance of other estimators available in the literature.
