Least Squares Method in Statistical Regression
The Least Squares Method in Statistical Regression is a foundational estimation technique within mathematical statistics that determines optimal parameter values for linear models by minimizing the sum of squared residuals between observed and predicted data points. This method relies on rigorous principles from calculus and linear algebra to derive closed-form solutions under assumptions of linearity, independence, homoscedasticity, and normal distribution of errors. As a core component of multivariate analysis, it provides the theoretical basis for quantifying relationships among multiple variables while serving as a precursor to more complex regression frameworks in predictive modeling.
