This study is an effort to investigate the asymmetric effects of privatization and digital economy on renewable energy consumption. The nonlinear quantile autoregressive distributed lag (QARDL) technique used estimate short long-run analysis. Findings QARDL model posit that positive shock in promotes consumption by increasing consumption, while negative demotes reducing In run, does not signifi...

Storyboard consisting of key-frames is a popular format of video summarization as it helps in efficient indexing, browsing and partial or complete retrieval of video. In this paper, we have presented a size constrained storyboard generation scheme. Given the shots i.e. the output of the video segmentation process, the method has two major steps: extraction of appropriate key-frame(s) from each ...

Background It is known that defects in the synthesis and structure of cytokines or their receptors can lead to modification many pathological processes organism: inflammation, coagulation, impaired cell regeneration, which makes it appropriate further study genetic preconditions for violation immunoregulatory mechanisms. Great attention paid allelic polymorphism genes chronic inflammatory disea...

A Wald test with enhanced selectivity capabilities is proposed in homogeneous environments. At the design stage, we assume that the cell under test contains a noise-like interferer in addition to colored noise and possible signal of interest. We show that the Wald test is equivalent to a recently proposed Rao test. We also observe that this Rao/Wald test possesses constant false alarm rate prop...

In this paper, we propose a new approach to test the hypothesis of long-run Granger non-causality in cointegrated systems. We circumvent the problem of singularity of the variance-covariance matrix associated with the usual Wald type test by proposing a generalized inverse procedure, and an alternative simple procedure which can be approximated by a suitable chi-square distribution. A test for ...

sional Runs Statistic. (Under the direction of DANA QUADE.) Friedman and Rafsky have generalized the runs statistic presented by Wald and Wolfowitz for testing the homogeneity of two populations to include the comparison of multivariate populations. Their multi-dimensional runs statistic can be defined as the number of links between observations from different populations, where observations ma...

The detection of differential item functioning (DIF) is an essential step in increasing the validity of a test for all groups. The item response theory (IRT) model comparison approach has been shown to be the most flexible and powerful method for DIF detection; however, it is computationally-intensive, requiring many model-refittings. The Wald test, originally employed by Lord for DIF detection...

The issue of the non-invariance of the Wald test under nonlinear reparametrisations of the restrictions under test is studied from a differential geometric viewpoint. Quantities that can be defined in purely geometrical terms are by construction invariant under reparametrisation, and various attempts are made to construct a Wald test out of such invariant quantities only. Despite the existence ...
