Abstract: Expansions of weighted pseudoinverses with mixed weights into matrix power series or power products with negative exponents are defined and analyzed. One of these matrices is positive definite and the other is nonsingular and indefinite.… read more here.

Abstract: While the spatial weights matrix $\boldsymbol{W}$ is at the core of spatial regression models, there is a scarcity of techniques for validating a given specification of $\boldsymbol{W}$. I approach this problem from a measurement error… read more here.
