In the paper, a selection of statistical tests for median are presented. In particular, parametric and nonparametric significance tests are considered. In the case of parametric tests the critical regions are constructed on the basis of the known populati... see more

When zeroes (or ties within pairs) occur in data being analyzed with a sign test or a signed rank test, nonparametric methods textbooks and software consistently recommend that the zeroes be deleted and the data analyzed as though zeroes did not exist. Th... see more

The information-theoretical concept transfer entropy is an ideal measure for detecting conditional independence, or Granger causality in a time series setting. The recent literature indeed witnesses an increased interest in applications of entropy-based t... see more

Statistical analysis of data sets is a necessary component of any medical research. Modern methods of mathematical statistics and statistical application suites provide extensive capabilities for analysis of random values. However, when a data set is repr... see more

Introduction: Application of statistical software typically does not require extensive statistical knowledge, allowing to easily perform even complex analyses. Consequently, test selection criteria and important assumptions may be easily overlooked or giv... see more

AbstractIn this article we assess the appropriateness of the constant volatility assumption required by the Black (1976) option pricing model for options on the All Share Index future. The assessment uses similar nonparametric tests as implemented in Rubi... see more

Fifteen sweet corn inbred lines and three su tester lines were used in testcrosses generating 45 F1 simple hybrids. GCA as well as SCA were computed based on performances of F1 hybrids in plant height, ear weight, ear length, number of rows/ear, number of... see more

Most often, in nominating promising genitors for apple breeding programs, their performance stability stands as a major criterion. This means that an increase in speed, accessibility and accuracy of performance stability evaluation will translate into mor... see more

Five apple cultivars (Florina, Golden Delicious, Idared, Jonathan and Starkrimson), were tested in 2004 and 2005 in five commercial orchards located in different counties of Transylvania with quite nonsimilar environments. Fruit yield was registered, the... see more
