Web • the ols estimators are obtained by minimizing residual sum squares (rss). Web the primary property of ols estimators is that they satisfy the criteria of minimizing the sum of squared residuals. 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; The first order conditions are @rss @ ˆ j = 0 ⇒ ∑n i=1 xij uˆi = 0; 1;:::;k) where ˆu is the residual. We have a system of k +1. 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. The diagonal is the sum of the squares of row i.
