research studies on PCA

Principal Component Analysis (PCA) is a statistical technique used in research to simplify complex data sets by identifying their most important features. Studies often use PCA to reduce large amounts of variables into fewer, meaningful components, making patterns and relationships easier to analyze. This method is common in fields like biology, psychology, and engineering, helping researchers uncover underlying structures without losing critical information. In essence, PCA helps turn complicated data into clearer insights, improving understanding and decision-making in various scientific investigations.
