Move the points so that they are in a circular shape.[br]How do the points appear when n = 1 and they are projected to PC1, PC2, or PC3? [br]
What is the variance and Explained variance ratio when points are projected onto PC1, PC2, and PC3? [br]
Switch the number of principal components to 2.[br]Which combination of two principal components best preserves the circular shape?
Compare the distance between the principal component planes and the points. Which two principal components create a plane that is closest to the most points?
How does the explained variance ratio relate to the distance the point are from the plane?
