Latent class modelling of respiratory outcomes in a South African birth cohort
… evaluate various statistical approaches for identifying latent structures and modelling longitudinal trajectories, tracking 1143 children until school age. To identify wheezing phenotypes, partition around medoids (PAM) clustering tailored for longitudinal data, latent class analysis …

Mechanisms of observed spatial heterogeneity in rainfall variability over the winter rainfall zone of South Africa
… despite such understanding being crucial for interpreting past and robustly projecting future climate change patterns. Hence, the spatial heterogeneity of WRZ rainfall is investigated in relation to regional rainfall systems and hemispheric climate drivers, using both gauge-based and …
