This article considers a new approximation to the log-likelihood surface in mixture models. This approximation is based on both the mean and variance of the full-data log-likelihood over imputations ...

One of the formulas in calculus is Newton’s Method Approximation Formula. This technique tries to find the root of an equation. It is a trial-and-erro ...

The variational inequality formulation provides a mechanism for determining both the option value and the early exercise curve implicitly (Jaillet, Lamberton and Lapeyre, 1990). Standard ...

This paper discusses certain common features of several algorithms for finding approximations to a zero of a mapping F: Rn → Rn. In particular, a recent simplicial pivot algorithm of the authors, ...
