Abstract
Flashover voltage estimation has been carried out
conventionally with the up-and down method by Dixon and Mood. Recently,
Hirose and Kato proposed a new version of the method to change the
way of analyzing data. Although the method has better properties
than the conventional one, it requires solving maximum likelihood
equations. In this paper we reduce the troublesome task (e.g. implementation
and the selection of a proper initial value) attendant on the requirement
by using the expectation-maximization (EM) algorithm that gives
a useful iterative formula to solve the equations. The iterative
formula almost always can give the solutions of the likelihood equations
because of its excellent global convergence of the EM algorithm.
