Objectives This study aimed to describe recent patterns in the types of statistical test used in original articles that were published in Journal of the Korean Association of Oral and Maxillofacial Surgeons. Materials and Methods Thirty-six original articles published in the Journal in 2015 and 2016 were ascertained. The type of statistical test was identified by one researcher. Descriptive s...

Abstract Studies detecting trends in climate elements typically concentrate on their local significance, ignoring the question whether significant may or not have occurred due to chance. The present paper fills this gap by examining several approaches statistical significance of defined a grid, that is regional scale. To end, we introduce novel simple procedure testing, which based counting sig...

Testing hypothesis is one of the most important problems in a nonparametric statistic. Various nonparametric test statistics have been proposed and discussed for a long time. We use the exact critical value for testing hypothesis when the sample sizes are small. However, for large sample sizes, it is very difficult to evaluate the exact critical value. Therefore, the limiting distributions of n...

In this paper we approach the analysis of statistics algorithms from a geometric viewpoint and use techniques from computational geometry to develop new, fast algorithms for computing familiar statistical quantities. Such fundamental procedures as sorting and selection play an important role in nonparametric estimation as well as in correlation and regression and we use known results to obtain ...

This paper make straightforward extensions to Anderson’s (1996) nonparametric statistical tests of stochastic dominance criteria to bivariate distributions. These test are applied to a time series of cross-section datasets on household level total expenditure and non labour market time in the UK.

Bhadradri district of the central Telangana zone is monsoon dependent as like our country in past three decades many changes and shifts rainfall was experienced by farming community. Hence, data (1991-2020) analyzed using non parametric statistical tests i.e Mann-Kendall (MK) test Sen’s slope estimator for determining trend magnitude. The Results study revealed that Z value annual significantly...

In this paper we analyze some properties of the discrete copulas in terms of permutations. We observe the connection between discrete copulas and the empirical copulas, and then we analyze a statistic that indicates when the discrete copula is symmetric and obtain its main statistical properties under independence. The results obtained are useful in designing a nonparametric test for symmetry o...

the discharge data used for hydrological modeling should be the long-term suitable random data without trend and jump which is followed a specific statistical distribution. in this study, the above mentioned conditions were evaluated for 31 years period (1974-2004) of annual mean discharge data of 10 gauging stations of west azarbaijan province. for this purpose, the non-parametric spearman cor...
