Joint Assessment of the Differential Item Functioning and Latent Trait Dimensionality of Students' National Tests
Michela Gnaldi, Francesco Bartolucci, Silvia Bacci
Within the educational context, students' assessment tests are routinely validated through Item Response Theory (IRT) models which assume unidimensionality and absence of Different…
A causal analysis of mother's education on birth inequalities
Silvia Bacci, Francesco Bartolucci, Luca Pieroni
We propose a causal analysis of the mother's educational level on the health status of the newborn, in terms of gestational weeks and weight. The analysis is based on a finite mixt…
A multidimensional latent class Rasch model for the assessment of the Health-related Quality of Life
Silvia Bacci, Francesco Bartolucci
The work describes a multidimensional latent class Rasch model and its application to data about the measurement of some aspects of Health-related Quality of Life and Anxiety and D…
Causal inference in paired two-arm experimental studies under non-compliance with application to prognosis of myocardial infarction
F. Bartolucci, A. Farcomeni
Motivated by a study about prompt coronary angiography in myocardial infarction, we propose a method to estimate the causal effect of a treatment in two-arm experimental studies wi…
MultiLCIRT: An R package for multidimensional latent class item response models
Francesco Bartolucci, Silvia Bacci, Michela Gnaldi
We illustrate a class of Item Response Theory (IRT) models for binary and ordinal polythomous items and we describe an R package for dealing with these models, which is named Multi…
Nested hidden Markov chains for modeling dynamic unobserved heterogeneity in multilevel longitudinal data
F. Bartolucci, M. Lupparelli
In the context of multilevel longitudinal data, where sample units are collected in clusters, an important aspect that should be accounted for is the unobserved heterogeneity betwe…
