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 comparison of some criteria for states selection in the latent Markov model for longitudinal data
Silvia Bacci, Silvia Pandolfi, Fulvia Pennoni
We compare different selection criteria to choose the number of latent states of a multivariate latent Markov model for longitudinal data. This model is based on an underlying Mark…
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…
Mixtures of equispaced normal distributions and their use for testing symmetry in univariate data
Silvia Bacci, Francesco Bartolucci
Given a random sample of observations, mixtures of normal densities are often used to estimate the unknown continuous distribution from which the data come. Here we propose the use…
A class of Multidimensional Latent Class IRT models for ordinal polytomous item responses
Silvia Bacci, Francesco Bartolucci, Michela Gnaldi
We propose a class of Item Response Theory models for items with ordinal polytomous responses, which extends an existing class of multidimensional models for dichotomously-scored i…
