1;:::;k) where ˆu is the residual. However, there are other properties. Web • the ols estimators are obtained by minimizing residual sum squares (rss). The diagonal is the sum of the squares of row i. The first order conditions are @rss @ ˆ j = 0 ⇒ ∑n i=1 xij uˆi = 0; We have a system of k +1. 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; Web this video provides a derivation of the form of ordinary least squares estimators, using the matrix notation of econometrics.
