OLS in Matrix Form
Web for a rectangular m × n matrix x, x0x is the n × n square matrix where a typical element is the sum of the cross products of the elements of row i and column j; Web • the ols estimators are obtained by minimizing residual sum squares (rss). The first order conditions are @rss @ ˆ j = 0 ⇒ ∑n i=1 xij uˆi = 0; However, there are other properties. Web this video provides a derivation of the form of ordinary least squares estimators, using the matrix notation of econometrics. 1;:::;k) where ˆu is the residual. We have a system of k +1. The diagonal is the sum of the squares of row i. Web the primary property of ols estimators is that they satisfy the criteria of minimizing the sum of squared residuals.
