LUCIDus: Integreted clustering with multi-view data Version 3.0.1


The LUCIDus package implements the statistical method LUCID proposed in the research paper A Latent Unknown Clustering Integrating Multi-Omics Data (LUCID) with Phenotypic Traits (Bioinformatics, 2020). LUCID conducts integrated clustering by using multi-view data, including exposures, and omics data with/without outcome. LUCIDus features variable selection, incorporating missingness in omics data, visualization of the LUCID model via Sankey diagram, bootstrap inference, and functions for tuning model parameters.

LUCID version 3.0.1, a major update and enhancement from the original release, implements different integration strategies for multi-omics data with multiple layers including LUCID early integration, LUCID in parallel, and LUCID in serial. It also incorporates methods to deal with missingness in multi-omics data. The following DAG illustrates the three different LUCID models for three integration strategies.
