posted on 1971-04-01, 00:00 authored by Franklin M. Fisher, Joseph B. KadaneIN THEIR ARTICLE [5], Liu and Breen propose a new estimator of the large-sample asymptotic
covariance matrix for the limited information maximum likelihood estimator in simultaneous
equations, and express surprise that their estimator is different from the estimator proposed
by Chernoff and Divinsky [1]. Additionally, they question the interpretation of a statistic
used in the past to test over-identifying restrictions.
