The Classical Least-Squares Model

  • Alejandro C. Olivieri
Chapter

Abstract

The simplest first-order multivariate model, based on classical least-squares, is discussed. Important concepts are introduced, which are common to other advanced models, such as the regression coefficients and the first-order advantage. The main limitations of the classical model are detailed.

Keywords
