An Alternating Moment Condition for Bi-freeness
In this note we demonstrate an equivalent condition for bi-freeness, inspired by the well-known “vanishing of alternating centred moments” condition from free probability. We show that all products satisfying a centred condition on maximal monochromatic χ-intervals have vanishing moments if and only if the family of pairs of faces they come from is bi-free. In addition, we construct a bi-free u...
متن کاملAdditional Moment Condition Tests ∗
The primary focus of this article is the provision of tests for additional conditional moment constraints in cross-section or short panel data contexts. The principal contribution is the explicit incorporation of conditional moment restrictions defining the maintained hypothesis in the formulation of the test statistics thus mirroring that of the classical parametric likelihood setting by defin...
متن کاملAn Alternating Direction Implicit Method for Modeling of Fluid Flow
This research includes of the numerical modeling of fluids in two-dimensional cavity. The cavity flow is an important theoretical problem. In this research, modeling was carried out based on an alternating direction implicit via Vorticity-Stream function formulation. It evaluates different Reynolds numbers and grid sizes. Therefore, for the flow field analysis and prove of the ability of the sc...
متن کاملGel Criteria for Moment Condition Models
GEL methods which generalize and extend previous contributions are defined and analysed for moment condition models specified in terms of weakly dependent data. These procedures offer alternative one-step estimators and tests that are asymptotically equivalent to their efficient two-step GMM counterparts. The basis for GEL estimation is via a smoothed version of the moment indicators using kern...
متن کاملOPTIMAL DESIGN OF COLUMNS FOR AN INTERMEDIATE MOMENT FRAME UNDER UNIAXIAL MOMENT AND AXIAL LOADS
The present study addresses optimal design of reinforced concrete (RC) columns based on equivalent equations considering deformability regulations of ACI318-14 under axial force and uniaxial bending moment. This study contrary to common approaches working with trial and error approach in design, at first presents an exact solution for intensity of longitudinal reinforcement in column section by...
