  "Description": "Provides Bayesian PCA, Probabilistic PCA, Nipals PCA,\nInverse Non-Linear PCA and the conventional SVD PCA. A cluster\nbased method for missing value estimation is included for\ncomparison. BPCA, PPCA and NipalsPCA may be used to perform PCA\non incomplete data as well as for accurate missing value\nestimation. A set of methods for printing and plotting the\nresults is also provided. All PCA methods make use of the same\ndata structure (pcaRes) to provide a common interface to the\nPCA results. Initiated at the Max-Planck Institute for\nMolecular Plant Physiology, Golm, Germany.",
