“…Using Structural Equation Modelling (SEM), the current study examines dependence and correlation between latent constructs, with particular attention to the effect of observed heterogeneity on the findings. In recent years, researchers have become more interested in the impact of heterogeneity on SEM, using Multiple Indicators Multiple Causes (MIMIC) models to explain heterogeneity in perceptions of latent constructs ( Allen et al, 2020 , Allen et al, 2019b , Allen et al, 2018 , de Oña, 2020 , de Oña, 2022 , Guirao et al, 2016 ), and Multi-Group Analysis (MGA) to explain differences in measurement and structural paths ( Allen et al, 2019a , Allen et al, 2019b , de Oña, 2022 ). Taking into account heterogeneity is crucial to achieving robust results in research on public transport ( de Oña, 2020 ), whose users usually possess a wide range of demographic, socio-economic, and travel pattern characteristics.…”
