PCA is a method that finds linear combinations (called Principal Components) within a data set with the goal of maximizing the amount of variation that is explained by those Principal Components.

WebbKey Results: Cumulative, Eigenvalue, Scree Plot. In these results, the first three principal components have eigenvalues greater than 1. These three components explain 84.1% of the variation in the data. The scree plot shows that the eigenvalues start to form a straight line after the third principal component. WebbPrincipal component analysis (PCA) is one popular approach analyzing variance when you are dealing with multivariate data. You have random variables X1, X2,...Xn which are all correlated (positively or negatively) to varying degrees, and you want to get a better understanding of what's going on. PCA can help.
