Agreement Threshold on Axelrod's model of Cultural Dissemination
Pádraig Mac Carron, Paul J. Maher, Susan Fennell +4
Shared opinions are an important feature in the formation of social groups. In this paper, we use the Axelrod model of cultural dissemination to represent opinion-based groups. In…
A modelling methodology for social interaction experiments
Susan C. Fennell, James P. Gleeson, Michael Quayle +2
Analysis of temporal network data arising from online interactive social experiments is not possible with standard statistical methods because the assumptions of these models, such…
An Alternative Formulation of Coxian Phase-type Distributions with Covariates: Application to Emergency Department Length of Stay
Jean Rizk, Kevin Burke, Cathal Walsh
In this paper we present a new methodology to model patient transitions and length of stay in the emergency department using a series of conditional Coxian phase-type distributions…
Penalized Variable Selection in Multi-Parameter Regression Survival Modelling
Fatima-Zahra Jaouimaa, Il Do Ha, Kevin Burke
Multi-parameter regression (MPR) modelling refers to the approach whereby covariates are allowed to enter the model through multiple distributional parameters simultaneously. This…
A Multi-parameter regression model for interval censored survival data
Defen Peng, Gilbert MacKenzie, Kevin Burke
We develop flexible multi-parameter regression survival models for interval censored survival data arising in longitudinal prospective studies and longitudinal randomised controlle…
Semiparametric multi-parameter regression survival modelling
Kevin Burke, Frank Eriksson, C. B. Pipper
We consider a log-linear model for survival data, where both the location and scale parameters depend on covariates and the baseline hazard function is completely unspecified. This…
Multi-Parameter Regression Survival Modelling: An Alternative to Proportional Hazards
Kevin Burke, Gilbert MacKenzie
It is standard practice for covariates to enter a parametric model through a single distributional parameter of interest, for example, the scale parameter in many standard survival…
A Flexible Parametric Modelling Framework for Survival Analysis
Kevin Burke, M. C. Jones, Angela Noufaily
We introduce a general, flexible, parametric survival modelling framework which encompasses key shapes of hazard function (constant, increasing, decreasing, up-then-down, down-then…
A Bivariate Power Generalized Weibull Distribution: a Flexible Parametric Model for Survival Analysis
M. C. Jones, Angela Noufaily, Kevin Burke
We are concerned with the flexible parametric analysis of bivariate survival data. Elsewhere, we have extolled the virtues of the "power generalized Weibull" (PGW) distribution as…
On the Non-uniqueness of Representations of Coxian Phase-Type Distributions
Jean Rizk, Kevin Burke, Cathal Walsh
Parameter estimation in Coxian phase-type models can be challenging due to their non-unique representation leading to a multi-modal likelihood. Since each representation correspond…
