Rank score tests.
Nonparametric statistical methods are useful tools for data analysis when there is reason to believe that the outcome variables of interest may fail certain distributional assumptions required for parametric methods. Variables may be ordered categories in nature and thereby not suitable for analysis methods that assume normally distributed variables, such as t tests or analyses of variance and ...
متن کاملGeometry of rank tests
We study partitions of the symmetric group which have desirable geometric properties. The statistical tests defined by such partitions involve counting all permutations in the equivalence classes. These permutations are the linear extensions of partially ordered sets specified by the data. Our methods refine rank tests of non-parametric statistics, such as the sign test and the runs test, and a...
متن کاملDeficiencies of combined rank tests
Ahs/rcrct: Oneand two sample problems are considered which are divided into subproblems, for each of which a separate rank statistic is obtained. The best combination of these statistics is then compared to the ordinary undivided rank statistic. One easily sees that, under natural conditions, splitting causes no first order efficiency loss. Hence it becomes interestmg to derive second order res...
متن کاملSpearman’s Rank Correlation Tests (Simulation)
2. Generate a random sample of points (X, Y) from the bivariate distribution specified by the alternative hypothesis. Calculate the test statistic from the simulated data and determine if the null hypothesis is accepted or rejected. These samples are used to calculate the power of the test. In the case of paired data, the individual values are simulated are constructed so that they exhibit the ...
متن کاملConvex Rank Tests and Semigraphoids
Convex rank tests are partitions of the symmetric group which have desirable geometric properties. The statistical tests defined by such partitions involve counting all permutations in the equivalence classes. Each class consists of the linear extensions of a partially ordered set specified by data. Our methods refine existing rank tests of non-parametric statistics, such as the sign test and t...
