Switch to 2D perspective and move the points so that they are in a straight line.[br]After switching back to 3D perspective, 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]
When points are oriented in a line, the EVR should be close to 1 when points are projected onto PC1 and close to 0 for PC2 and PC3. Why do you think this occurs?
