In the following table, each value in column pca_1, pca_2, and pca_3 is calculated by multiplying corresponding attribute values in the input table (Input) and output table (Output (Table of Eigenvectors), Output (Table of Eigenvectors)) and then adding those products. (The attribute values are in columns age through hdl.)

For example, for pid 1:

pca_1 = 50 * 0.023353196 + 33.6 * 0.005049565 + 72 * 0.001586694 + 148 * 0.084203226 + 6 * (- 0.00859257) + 35* 0.041332922+ 0 * 0.995263409 + 62.7 * 0.00222103 = 15.4479999925239
