  1. Continuous-Time Markov Chain Modeling

    As we mentioned earlier, the Russian mathematician Andrei Andreyevich Markov (1856–1922) introduced sequences of values of a random variable in which...

  2. A copula formulation for multivariate latent Markov models

    We specify a general formulation for multivariate latent Markov models for panel data, where outcomes are possibly of mixed-type (categorical,...

    Article Open access 07 February 2024
  3. Variable Selection for Hidden Markov Models with Continuous Variables and Missing Data

    We propose a variable selection method for multivariate hidden Markov models with continuous responses that are partially or completely missing at a...

    Article Open access 23 January 2024
  4. Hidden Markov models for longitudinal rating data with dynamic response styles

    This work deals with the analysis of longitudinal ordinal responses. The novelty of the proposed approach is in modeling simultaneously the temporal...

    Article Open access 28 September 2023
  5. Multivariate Hidden Markov Models

    This chapter provides three extended example analyses, applying hidden Markov models to multivariate time series. The first example (Sect. 6.1)...

  6. Hidden Markov Models

    This chapter introduces hidden Markov models (HMMs), which can be viewed as an extension of mixture models, in which a unit of observation (e.g., a...

  7. Bayesian Analysis of First-Order Markov Models for Autocorrelated Binary Responses

    In many clinical trials, patient outcomes are often binary-valued which are measured asynchronously over time across various dose levels. To account...

    Dasom Lee, Sujit Ghosh in Journal of Statistical Theory and Practice
    Article 23 November 2022
  8. Markov switching stereotype logit models for longitudinal ordinal data affected by unobserved heterogeneity in responding behavior

    When asked to assess their opinion about attitudes or perceptions on Likert-scale, respondents often endorse the midpoint or extremes of the scale...

    Roberto Colombi, Sabrina Giordano in AStA Advances in Statistical Analysis
    Article Open access 15 May 2024
  9. Discrete-Time Markov Chain

    Markov chains serve as one of the most important methods in the application of probability theory to real-world models involving uncertainty. Markov...

  10. Markov switching quantile regression models with time-varying transition probabilities

    Markov switching models are widely used in the time series field for their ability to describe the impact of latent regimes on the behaviour of...

    Article 16 February 2022
  11. The Latent Markov Chain Model

    The latent Markov chain model is discussed, and the relationship between the model and the latent class model is considered. An ML estimation...

  12. A hybrid landmark Aalen-Johansen estimator for transition probabilities in partially non-Markov multi-state models

    Multi-state models are increasingly being used to model complex epidemiological and clinical outcomes over time. It is common to assume that the...
