Estimating Equations for Density Dependent Markov Jump Processes

open access: yesMathematics, 2021
Reaction networks are important tools for modeling a variety of biological phenomena across a wide range of scales, for example as models of gene regulation within a cell or infectious disease outbreaks in a population. Hence, calibrating these models to

On generalised estimating equations for vector regression [PDF]

open access: yesAustralian & New Zealand Journal of Statistics, 2017
Generalized estimating equations (GEE; Liang & Zeger 1986) for general vector regression settings are examined. When the response vectors are of mixed type (e.g. continuous-binary response pairs), the GEE approach is a semiparametric alternative to full-likelihood copula methods, and is closely related to the mean-covariance estimation equations ...
