Four classic PCA algorithms: NIPALS, the power method (POWER), singular value decomposition (SVD) and eigenvalue decomposition (EVD) are modified into their kernel version to analyse wide data sets. For such data sets with many variables and fewer objects, the classic algorithms become very ineffici
