Estimating cell probabilities in contingency tables with constraints on marginals/conditionals by geometric programming with applications

Wang, Xinlei; Lim, Johan; Kim, Seung-Jean; Hahn, Kyu - In: Computational Statistics 30 (2015) 1, pp. 107-129

<Para ID="Par1">Contingency tables are often used to display the multivariate frequency distribution of variables of interest. Under the common multinomial assumption, the first step of contingency table analysis is to estimate cell probabilities. It is well known that the unconstrained maximum likelihood...</para>

Analysing sojourn times in queueing networks: A structural approach

Heidergott, Bernd - In: Computational Statistics 52 (2000) 1, pp. 115-132

Structural properties of generalised semi-Markov processes (GSMP) have been successfully studied in the literature. Examples are the celebrated commuting condition (CC), which is the key condition for unbiasedness of the infinitesimal perturbation analysis (IPA) gradient estimator, or the...
