Dealing with separation problem in hidden Markov models with covariates based on a penalized maximum likelihood approach
Luca Brusa, Fulvia Pennoni, Francesco Bartolucci +1
A penalized maximum likelihood estimation approach is proposed for discrete-time hidden Markov models where covariates affect the observed responses and serial dependence is consid…
Maximum likelihood estimation of hidden Markov models for continuous longitudinal data with missing responses and dropout
Silvia Pandolfi, Francesco Bartolucci, Fulvia Pennoni
We propose an inferential approach for maximum likelihood estimation of the hidden Markov models for continuous responses. We extend to the case of longitudinal observations the fi…
LMest: an R package for latent Markov models for categorical longitudinal data
Francesco Bartolucci, Alessio Farcomeni, Silvia Pandolfi +1
Latent Markov (LM) models represent an important class of models for the analysis of longitudinal data (Bartolucci et. al., 2013), especially when response variables are categorica…
Exploiting TIMSS and PIRLS combined data: multivariate multilevel modelling of student achievement
Leonardo Grilli, Fulvia Pennoni, Carla Rampichini +1
We exploit a multivariate multilevel model for the analysis of the Italian sample of the TIMSS\&PIRLS 2011 Combined International Database on fourth grade students. The multivariat…
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…
Mixture latent autoregressive models for longitudinal data
Francesco Bartolucci, Silvia Bacci, Fulvia Pennoni
Many relevant statistical and econometric models for the analysis of longitudinal data include a latent process to account for the unobserved heterogeneity between subjects in a dy…
