About the Oral Health of Bulgarian Population over 20 Years Old [PDF]

, 2011
2000 Mathematics Subject Classification: 62P10, 62J12.Caries is the most widespread dental disease around the world. Thus, caries prevalence and intensity are repeatedly studied.

Markov modeling on dynamic state space for genetic disorders and infectious diseases with mutations: Probabilistic framework, parameter estimation, and applications

Computational and Mathematical Biophysics
The emergence and dynamic prevalence of genetic disorders and infectious diseases with mutations pose significant challenges for public health interventions.

Analysing and Monitoring Surveillance Data of Mumps in Bulgaria [PDF]

, 2011
2000 Mathematics Subject Classification: 62P10.This paper aims to present the applicability of the Bayesian methodology for monitoring surveillance data collected for vaccine-preventable diseases, like mumps, measles and possibly others.

A causal framework for the self-controlled case series design

Journal of Causal Inference
Vaccine safety surveillance programs that monitor possible short-term rare adverse events following vaccination usually only have access to data on vaccinated individuals who experienced the event of interest.

Smoothing-inspired lack-of-fit tests based on ranks

, 2008
A rank-based test of the null hypothesis that a regressor has no effect on a response variable is proposed and analyzed. This test is identical in structure to the order selection test but with the raw data replaced by ranks. The test is nonparametric in

Beyond conditional averages: Estimating the individual causal effect distribution

Journal of Causal Inference
In recent years, the field of causal inference from observational data has emerged rapidly. The literature has focused on (conditional) average causal effect estimation.

Mediation analyses for the effect of antibodies in vaccination

Journal of Causal Inference
We review standard mediation assumptions as they apply to identifying antibody effects in a randomized vaccine trial and propose new study designs to allow the identification of an estimand that was previously unidentifiable. For these mediation analyses,

Time to a single hybridization event in a group of species with unknown ancestral history

, 2012
We consider a stochastic process for the generation of species which combines a Yule process with a simple model for hybridization between pairs of co-existent species.

Bayesian hierarchical models for analysing the spatial distribution of bioclimatic indices [PDF]

, 2017
A methodological approach for modelling the spatial distribution of bioclimatic indices is proposed in this paper. The value of the bioclimatic index is modelled with a hierarchical Bayesian model that incorporates both structured and unstructured random

Indirect inference for survival data [PDF]

, 2003
In this paper we describe the so-called “indirect” method of inference, originally developed from the econometric literature, and apply it to survival analyses of two data sets with repeated events.
