- A comparison of unsupervised methods based on dichotomous data to identify clusters of airways symptoms: latent class analysis and partitioning around medoids methodsPublication . Amaral, Rita; Jacinto, Tiago; Pereira, Ana; Almeida, Rute; Fonseca, JoãoLatent class analysis (LCA) and partitioning around medoids (PAM) are popular data-driven methods for partitioning objects based on dichotomous data, remaining not clear which is better for large epidemiological datasets.
