Multiomics Data Integration
Provides functions to do 'O2PLS-DA' analysis for multiple omics data integration.
The algorithm came from "O2-PLS, a two-block (X±Y) latent variable regression (LVR) method with an integral OSC filter"
which published by Johan Trygg and Svante Wold at 2003 <10.1002>.
'O2PLS' is a bidirectional multivariate regression method that aims to separate the covariance between
two data sets (it was recently extended to multiple data sets) (Löfstedt and Trygg, 2011 <10.1002>; Löfstedt et al., 2012 <10.1016>)
from the systematic sources of variance being specific for each data set separately.10.1016>10.1002>10.1002>
