BPCA_dostep

Data structure containing all needed information. See the
source documentation of BPCA_initmodel for details


The function contains the actual implementation of the BPCA
component  estimation. It performs one step of the BPCA EM
algorithm.  It is called 'maxStep' times from within the main loop
in BPCAestimate.


Provides Bayesian PCA, Probabilistic PCA, Nipals PCA,
Inverse Non-Linear PCA and the conventional SVD PCA. A cluster
based method for missing value estimation is included for
comparison. BPCA, PPCA and NipalsPCA may be used to perform PCA
on incomplete data as well as for accurate missing value
estimation. A set of methods for printing and plotting the
results is also provided. All PCA methods make use of the same
data structure (pcaRes) to provide a common interface to the
PCA results. Initiated at the Max-Planck Institute for
Molecular Plant Physiology, Golm, Germany.
