Based on the asymmetric copula function, this paper analyzes static and dynamic correlation between Shanghai Composite Index Shenzhen Index. Through analysis, it is found that function better than Gumbel Copula in describing distribution characteristics of top tail dependence Index, coefficient definition based can well describe variables. In time-varying improves traditional evolution equation...

[Purpose] To study the correlation of the results obtained from different proprioception test methods, namely, the joint angle reset method, the motion minimum threshold measurement method, and the force sense reproduction method, performed on the same subjects' knees. [Subjects and Methods] Different proprioception test methods, the joint angle reset method, the motion minimum threshold measur...

Using real time student response systems (clickers) in Management Information Systems classes (as well as in other disciplines) has previously been shown to lead to better student engagement and better student performance. This paper considers how the students’ overall performance in the class correlates with the students’ performance on various assessment tools used in the class. For medium si...

Cutaneous delayed hypersensitivity to antigens prepared from Sporothrix schenckii and several Ceratocystis species, including C. stenoceras, C. ulmi, C. ips, and C. minor, was tested in 14 patients with known cutaneous sporotrichosis. Extensive cross-reactions were observed. Nonsporotrichotic people (controls) did not react to these antigens. The correlation coefficient between antigens of S. s...

The variance–covariance matrix is a multi-dimensional array of numbers, containing information about the individual variabilities and pairwise linear dependence set variables. However, itself difficult to represent in concise way, particularly context multivariate autoregressive conditional heteroskedastic models. common practice report plots k(k−1)/2 time-varying covariances, where k number ma...

introduction: the present age is the age of dramatic changes in technologies whose intellectual structure deepens information and considers creative and knowledge-oriented human resource participation. the present study has been performed to determine the relationship between knowledge management and creativity among the librarians of university libraries of shiraz, iran in 2010. methods: all f...

air pollution is a problem in kathmandu, nepal. particulate matter concentrations often exceed threshold values at which human health is severely affected. the problem is serious since it is in the valley topography wherein the meteorological parameters role is significant. this study addresses the linkages between meteorological processes and air pollution in the lower atmosphere of the kathma...

We study the existence theory for parabolic variational inequalities in weighted L spaces with respect to excessive measures associated with a transition semigroup. We characterize the value function of optimal stopping problems for finite and infinite dimensional diffusions as a generalized solution of such a variational inequality. The weighted L setting allows us to cover some singular cases...

Previous studies dealing with network theory focused mainly on the static aggregation of edges over specific time window lengths. Thus, most of the dynamic information gets lost. To assess the quality of such a static aggregation the temporal correlation coefficient can be calculated. It measures the overall possibility for an edge to persist between two consecutive snapshots. Up to now, this m...

Despite the relevance of correlational studies for most research domains, many students, teachers, and researchers alike hold misconceptions concerning the Pearson product-moment correlation coefficient. One of these, the transitivity misconception, has not yet been documented in a systematic way. This paper summarizes the first empirical study, using 279 university students, and examines the r...
