Principal Components Scoring This algorithm maps a dataset into the subspace generated by the principal components. If A = dataset to be scored, and B = eigenvector matrix (rows = features, cols = components), then the score is simply A * B, assuming the column features match up exactly. PCA on Wikipedia
