Applications Using Linear Models
Applications using linear models have become ubiquitous across various fields, serving as powerful tools for analyzing relationships between variables and making predictions. Whether in economics, engineering, social sciences, or beyond, linear models offer a versatile framework for understanding complex phenomena and making data-driven decisions. By representing relationships in terms of linear equations, these models enable practitioners to interpret trends, estimate parameters, and extrapolate outcomes with precision and clarity. In this introduction, we explore the diverse applications of linear models, highlighting their significance in driving insights, informing strategies, and advancing knowledge across disciplines.
