Principal Component Analysis (PCA)

Q: What is Principal Component Analysis?

Principal Component Analysis (PCA) is a statistical technique that converts correlated variables into a smaller set of uncorrelated variables, called principal components, that capture most of the variance in the original data. Expanded Explanation 1. Technical Function and Core Characteristics PCA performs a linear transformation of a dataset into orthogonal components that successively maximize variance. It computes eigenvalues and eigenvectors of a covariance or correlation matrix, or uses

Principal component analysis is a statistical dimensionality reduction technique that converts correlated variables into uncorrelated principal components, enabling enterprises to simplify high-dimensional datasets, reduce computational load, and support more stable modeling and analytics in machine learning and business intelligence workflows.
