Estimating Multiple Classification Latent Class Models [PDF]

Psychometrika, 1999
This paper presents a new class of models for persons-by-items data. The essential new feature of this class is the representation of the persons: every person is represented by its membership to multiple latent classes, each of which belongs to one latent classification.

Heterogeneity in mode choice behavior: A spatial latent class approach based on accessibility measures

Journal of Transport and Land Use, 2023
We propose a method to estimate mode choice models, where preference parameters are sensitive to the spatial context of the trip origin, challenging traditional assumptions of spatial homogeneity in the relationship between travel modes and the built ...

Dependent Latent Class Models

Bayesian Analysis, 2022
Latent Class Models (LCMs) are used to cluster multivariate categorical data (e.g. group participants based on survey responses). Traditional LCMs assume a property called conditional independence. This assumption can be restrictive, leading to model misspecification and overparameterization.
