Two matrices are generated (P and T)
As in other posts, we are going to look to the loadings & scores, for firsts three principal components:
In the following plot, I compare the loadings plots for the first 3 PCs calculated with SVD (up) and with NIPALS (down):
We can see how the first PC (PC1) has the same shape for both. The other two (PC2 & PC3) has also the same shape, but inverted).
Let´s compare the scores plots:
Red dots for NIPALS, black for SVD:
