Unsupervised Multiblock Methods

Source: R/unsupervised.R

Collection of unsupervised multiblock methods:

  • SCA - Simultaneous Component Analysis (sca)

  • GCA - Generalized Canonical Analysis (gca)

  • GPA - Generalized Procrustes Analysis (gpa)

  • MFA - Multiple Factor Analysis (mfa)

  • PCA-GCA (pcagca)

  • DISCO - Distinctive and Common Components with SCA (disco)

  • HPCA - Hierarchical Principal component analysis (hpca)

  • MCOA - Multiple Co-Inertia Analysis (mcoa)

  • JIVE - Joint and Individual Variation Explained (jive)

  • STATIS - Structuration des Tableaux à Trois Indices de la Statistique (statis)

  • HOGSVD - Higher Order Generalized SVD (hogsvd)

Details

Original documentation of STATIS: statis. JIVE, STATIS and HOGSVD assume variable linked matrices/data.frames, while SCA handles both links.

Examples

# Object linked data
data(potato)
potList <- as.list(potato[c(1,2,9)])
pot.sca    <- sca(potList)

# Variable linked data
data(candies)
candyList <- lapply(1:nlevels(candies$candy),function(x)candies$assessment[candies$candy==x,])
can.statis <- statis(candyList)
plot(can.statis$statis)
