Samples from the Attraction Indian Buffet Distribution
Description
Samples are provided from a latent feature allocation model using the
Attraction Indian Buffet Distribution (Warr et al., 2022) as a prior
distribution. The purpose of the model was to use pairwise distance
information to identify and predict the presence of Alzheimer's disease in
patients.
Usage
data(samplesFA)
Format
An object of class ‘list’ containing 100 posterior samples
from Warr et al. (2022)'s analysis. Each list elements encodes one feature
allocation as a binary matrix, with items in the rows and features
in the columns. These 100 feature allocation samples are a
subset of the original 1000 samples obtained using MCMC in the original
simulation study described by Warr et al. (2022).
