Statistical Behavior and Symmetry Tests
Symmetries and statistical properties in nuclei are closely related. The most striking example is the extremely large enhancement of parity violation in neutron resonances. Statistical distributions can provide information about the underlying character of nuclear properties. Level statistics and electromagnetic transition distributions have been used successfully to provide unique tests of pre...
متن کاملNonparametric symmetry tests for statistical functionals
Dedicated to the 70th birthday of Johann Pfanzagl Summary. Along the lines of Pfanzagl's work the testing theory for the non-parametric null hypothesis of symmetry (including matched pairs) is developed. The testing problem is typically given by a skew symmetric statistical functional which seems to be adequate for the nonparametric world. Under mild regularity assumptions asymptotically maximi...
متن کاملSymmetry of Nonparametric Statistical Tests on Three Samples
Problem statement: Many different nonparametric statistical procedures can be used to analyze ranked data. Inconsistencies among the outcomes of such procedures can occur when analyzing the same ranked data set. Understanding why these peculiarities can occur is imperative to providing an accurate analysis of the ranking data. In this context, this study addressed why inconsistent outcomes can ...
متن کاملOn Consistent Nonparametric Statistical Tests of Symmetry Hypotheses
Being able to formally test for symmetry hypotheses is an important topic in many fields, including environmental and physical sciences. In this paper, one concentrates on a large family of nonparametric tests of symmetry based on Cramér–von Mises statistics computed from empirical distribution and characteristic functions. These tests possess the highly desirable property of being universally ...
متن کاملSome Tests of Symmetry ·e Some Tests of Symmetry
CARL NOBUO YOSHIZAWA. Some Tests of Symmetry. (Under the direction of C.L DAVIS) Three nonparametric tests of symmetry about an unknown value are considered for continuous univariate distributions. Each test statistic is defined as the difference between the sample mean and an estimator of the median. Two of the median estimators are special cases of general quantile estimators which were propo...
