ANOVA-Simultaneous Component Analysis is used to understand how different parts of a complex system interact with each other. It helps to identify which parts are most important for the overall performance of the system, and which parts are having the biggest impact on its performance. For example, it can be used to figure out why your car isn't driving as well as it could be. It looks at multiple components in the car (like the engine, brakes, and tires), and looks at how they each interact with each other and affect the performance of the car. By looking at how each part of the system affects the overall performance, you can figure out what needs to be improved or changed in order to make your car go faster.
