  A. Use basic matrix operations and the algebra of matrices in practical problems. Possible applications may be drawn from areas such as Kirchoff’s laws, Leontieff model of an interacting economy, Markov chains, method of least squares, singular value decomposition and Fourier coefficients of a function.

  In the previous reading assignment the ordinary least squares (OLS) estimator for the simple linear regression case, only one independent variable (only one x), was derived. The procedure relied on combining calculus and algebra to minimize of the sum of squared deviations.

  The Least-Squares Criterion. The goal in simple linear regression is to determine the equation of the line that minimizes the total unexplained variation in the observed values for Y, and thus maximizes the variation in Y explained by the model. However, the residuals, which represent the unexplained variation, sum to zero.
