Modeling Space-Time Data Using Stochastic Differential Equations [PDF]

, 2009
This paper demonstrates the use and value of stochastic differential equations for modeling space-time data in two common settings. The first consists of point-referenced or geostatistical data where observations are collected at fixed locations and ...

BMI growth trajectory from birth to 5 years and its sex-specific association with prepregnant BMI and gestational weight gain

Frontiers in Nutrition, 2023
ObjectiveThe purpose of the study was to identify the latent body mass index (BMI) z-score trajectories of children from birth to 5 years of age and evaluate their sex-specific association with prepregnant BMI and gestational weight gain (GWG ...

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

Determining the Number of Latent Classes in Single- and Multiphase Growth Mixture Models [PDF]

Structural Equation Modeling: A Multidisciplinary Journal, 2014
Stage-sequential (or multiphase) growth mixture models are useful for delineating potentially different growth processes across multiple phases over time and for determining whether latent subgroups exist within a population. These models are increasingly important as social behavioral scientists are interested in better understanding change processes ...

Trajectories of Depressive Symptoms and Neighborhood Changes from Adolescence to Adulthood: Latent Class Growth Analysis and Multilevel Growth Curve Models [PDF]

International Journal of Environmental Research and Public Health, 2020
The role of neighborhood socioeconomic status (SES) and racial/ethnic composition on depression has received considerable attention in the United States. This study examines associations between trajectory patterns of neighborhood changes and depressive symptoms using data from Waves I-IV of the National Longitudinal Study of Adolescent to Adult Health.
