WebDec 3, 2024 · We propose here a Grade of Membership (GoM) model tailored for Bernoulli presence - absence matrix. We discuss the algorithmic details of the EM algorithm underlying this model. In ecological abundance study, reserachers often analyse the presence - absence data matrix marking a site \(i\) and a species \(j\) as 1, if the site \(i\) … WebGeneralizing Grade of Membership models for multivariate categorical data, we propose a new structure that groups the pobserved variables in the following sense: any subject’s latent membership is the same for variables within a group but can di er across groups.
