We consider the problem of model selection in vector autoregressive model with Normal innovation. Tests such as Vuong's and Cox's tests are provided for order and model selection, i.e. for selecting the order and a suitable subset of regressors, in vector autoregressive model. We propose a test as a modified log-likelihood ratio test for selecting subsets of regressors. The Europe oil prices, ...

background: cardiac involvement in systemic sclerosis (ssc) is more prevalent than previously thought. in this study, the frequency and severity of cardiovascular involvement were assessed in ssc patients referred to firouzgar hospital. methods: fifty-eight patients with ssc, selected from the data bank of ssc patients, were reviewed for the frequency and severity of 8 organ involvements in thi...

Subset assertions provide a declarative and natural means for expressing solutions to many problems involving sets. This paper is motivated by the use of subset assertions for formulating transitive closures and solving containment constraints in applications of graph traversal and program analysis. In these applications , circular containment constraints may arise, for which we propose an oper...

in this paper, we extend the construction of a fuzzy subgroup generated by a fuzzy subset to $l$-setting. this construction is illustrated by an example. we also prove that for an $l$-subset of a group, the subgroup generated by its level subset is the level subset of the subgroup generated by that $l$-subset provided the given $l$-subset possesses sup-property.

Abstract In [T. Dominguez Benavides and E. Llorens-Fuster, Iterated nonexpansive mappings, J. Fixed Point Theory Appl. 20 (2018), no. 3, Paper No. 104, 18 pp.], the authors raised question about existence of a fixed point free continuous INEA mapping T defined on closed convex bounded subset (or weakly compact subset) Banach space with normal structure. Our main goal is to give affirmative answ...
