Principal Component Analysis (PCA)

Principal component analysis

Principal component analysis (PCA) is a statistical technique used to reduce the dimensionality of large datasets while preserving the maximum amount of information. It involves transforming the data into a new coordinate system where the variation in the data can be described with fewer dimensions. PCA is commonly used for exploratory data analysis, making predictive models, and dimensionality reduction.
