Abstract
Recent advances in the theory of Edgeworth expansion allow rigorous estimation of remainder terms, under explicit regularity conditions. However, even in the important case of Student's $t$ statistic, the moment conditions required are unrealistically stringent. In this note we relax those conditions to the minimum needed to define terms in the Edgeworth expansion.
