Abstract: Analysis of time series data addresses the question on mechanisms underlying normal physiology and its alteration under pathological conditions. However, adding time variable to high-dimension, collinear, noisy data is a challenge in terms of mining… read more here.

DOI: 10.1007/s11222-024-10446-0
Abstract: The collection of data on populations of networks is becoming increasingly common, where each data point can be seen as a realisation of a network-valued random variable. Moreover, each data point may be accompanied by… read more here.

Abstract: Multilevel compositional data are data that are repeatedly measured or clustered within groups, and are nonnegative and sum to a constant value. These data arise in various settings, such as intensive, longitudinal studies using ecological… read more here.

A general Bayesian multilevel multidimensional IRT model for locally dependent data
Sign Up to like & getrecommendations! Published in 2018 at "British Journal of Mathematical and Statistical Psychology"
DOI: 10.1111/bmsp.12133
Abstract: Many item response theory (IRT) models take a multidimensional perspective to deal with sources that induce local item dependence (LID), with these models often making an orthogonal assumption about the dimensional structure of the data.… read more here.

DOI: 10.1155/2020/8749753
Abstract: In sub-Saharan Africa, 72% of pregnant women received an antenatal care visit at least once in their pregnancy period. Ethiopia has one of the highest rates of maternal mortality in sub-Saharan African countries. So, this… read more here.
