  1. Modeling and Analysis of Repeated Ordinal Data Using Copula Based Likelihoods and Estimating Equation Methods

    Kurada, Raghavendra Rao2019

    … The second part of the dissertation outlines the estimating equations approach for the analysis of longitudinal ordinal data for these non-likelihood models. We study the asymptotic properties of the estimates for both likelihood and non-likelihood methods. Comparisons based on simulations show …

Employing a generalized estimating equation with logit and poisson specifications, the results show that change towards democracy decreases the probability of involvement in militarized inter-state disputes and wars. However, uneven or "rocky" transitions are found to …
