Improved heteroscedasticity‐consistent covariance matrix estimators
(2000)
The heteroscedasticity‐consistent covariance matrix estimator proposed by White (1980) is commonly used in practical applications and is implemented into a number of pieces of statistical software. However, although ...
A class of improved heteroskedasticity-consistent covariance matrix estimators
(Escola de Pós-Graduação em Economia da FGV, 2002-09-05)
The heteroskedasticity-consistent covariance matrix estimator proposed by White (1980), also known as HC0, is commonly used in practical applications and is implemented into a number of statistical software. Cribari–Neto, ...
Matrix composition and corridor function for austral thrushes in a fragmented temperate forest
(Springer, 2013)
Although it is widely recognized that
animal movement may be facilitated by corridors
and hindered by the matrix, the influence of matrix
composition on the use of corridors still remain poorly
understood. We used ...
Modeling the micro-indentation of metal matrix composites
(Elsevier Science Sa, 2007-08)
A finite element model is developed to quantify the effect of the depth and diameter of the reinforcement in the hardness number of metal matrix composite. The model includes a spherical indenter pressed against a metal ...
The determinant of the distance matrix of graphs with blocks at most bicyclic
(Elsevier Science Inc., 2021-04-01)
Let G be a connected graph on n vertices and D(G) be its distance matrix. The formula for computing the determinant of this matrix in terms of the number of vertices is known when the graph is either a tree or a unicyclic ...
Psychometric Properties of the Dating Violence Questionnaire: Reviewing the Evidence in Chilean Youths

On quantum integrability of the Landau-Lifshitz model
(AMER INST PHYSICS, 2009)
We investigate the quantum integrability of the Landau-Lifshitz (LL) model and solve the long-standing problem of finding the local quantum Hamiltonian for the arbitrary n-particle sector. The particular difficulty of the ...
