We studied the limiting spectral distribution of large-dimensional sample covariance matrices of a stationary and invertible VARMA(p,q) model. Relationship of the power spectral density and limiting spectral distribution of large population dimensional covariance matrices of ARMA(p,q) is established. The equation about Stieltjes transform of large-dimensional sample covariance matrices is also ...

In this paper, we study the asymptotic distribution of a simple two-stage (Hannan-Rissanen-type) linear estimator for stationary invertible vector autoregressive moving average (VARMA) models in the echelon form representation. General conditions for consistency and asymptotic normality are given. A consistent estimator of the asymptotic covariance matrix of the estimator is also provided, so t...

For a quasi-split classical group over p-adic field with sufficiently large residual characteristic, we prove that the maximum depth of representation in each L-packet equals corresponding L-parameter. Furthermore, for unitary groups, show is constant L-packet. The key an analysis endoscopic character relation via harmonic based on Bruhat–Tits theory. These results are slight generalizations re...

We review experimental attempts using polarized neutron scattering technique to reveal the existence in high temperature superconductors of a long-range ordered state characterized by the spontaneous appearance of current loops. We draw a particular attention to our recent results (B. Fauqué et al., Phys. Rev. Lett. 96, 197001 (2006)) that, up to now, can be explained only by the theory of circ...

This paper analyses identification for multivariate unobserved components models in which the innovations to trend and cycle are correlated. We address order and rank criteria as well as potential non-uniqueness of the reduced-form VARMA model. Identification is shown for lag lengths larger than one in case of a diagonal vector autoregressive cycle. We also discuss UC models with common feature...

The degree of addictive substance usage score and three personality variables, namely, authoritarianism, alienation, and anomie were measured in 197 university students through a self-administered questionnaire. WHO's Youth Survey Questionnaire for drag use, Varma et al.'s scale of Authoritarianism, Srole's scale of Anomie, and Pearlin's scale of Alienation, were used. A study of the relationsh...
