Examining the determinants of efficiency using a latent class stochastic frontier model [PDF]

, 2015
In this study, we combine the latent class stochastic frontier model with the complex time decay model to form a single-stage approach that accounts for unobserved technological differences to estimate efficiency and the determinants of efficiency.

A Latent Class Growth Model for Migrants’ Remittances: An Application to the German Socio-Economic Panel [PDF]

Journal of the Royal Statistical Society Series A: Statistics in Society, 2019
SummaryWe propose a latent class mixture growth model with concomitant variables to study the time profiles of international remittances sent by first-generation migrants in Germany from 1996 to 2012. The latent class approach enables us to identify homogeneous subgroups of migrants associated with different trajectories for their remitting behaviour ...

The dynamics of adolescents’ pornography use and psychological well-being: a six-wave latent growth and latent class modeling approach

European Child & Adolescent Psychiatry, 2019
Despite increasing concerns that pornography decreases adolescents' well-being, existing empirical support for this position is largely limited to cross-sectional studies. To explore possible links between adolescent pornography use and psychological well-being more systematically, this study focused on parallel dynamics in pornography use, self-esteem
