the purpose of this work is to promote and facilitate forensic profiling and chemical analysis of illicit drug samples in order to determine their origin, methods of production and transfer through the country. the article is based on the gas chromatography analysis of heroin samples seized from three different locations in serbia. chemometric approach with appropriate statistical tools (multip...

This correspondence describes a new test for multivariate normality useful in pattern recognition. The test is based on the Friedman-Rafsky multivariate extension of the Wald-Wolfowitz runs test. We perform Monte-Carlo experiments to determine if the test is reliable in high dimensions with moderate sample size. We compare the test to some other tests mentioned in the literature.

The purpose of this study was to determine the role learning management as a soft skill in enhancing professionalism teachers Central Maluku, Indonesia. We conducted descriptive quantitative approach. Selected participants (N=40) involved filling out closed-questionnaire (35 favorable questions). Then, we examined our hypotheses using Wald- Wolfowitz run test. found that has teacher professiona...

“Oscillations” occur in quite different kinds of many-particle-systems when two groups of particles with different directions of motion meet or intersect at a certain spot. In this work a model of pedestrian motion is presented that is able to reproduce oscillations with different characteristics. The Wald-Wolfowitz test and Gillis’ correlated random walk are shown to include observables that c...

The result by Dvoretzky, Wald, and Wolfowitz on the sufficiency of nonrandomized decision rules for statistical decision problems with nonatomic state distributions holds for arbitrary Borel decision sets and for arbitrary measurable loss functions.

In this study, we use the Wald–Wolfowitz runs test as a statistical diagnosis tool to check whether randomness of residual for Morgan-Mercer-Flodin (MMF) utilized in fitting prediction cumulative death cases Nigeria owing COVID-19. The revealed that there were 13 total runs, however number should have been expected based on randomization assumption was 26. Because p-value less than 0.05, can co...
