Tests on asymmetry for ordered categorical variables

Klein, Ingo; Doll, Monika - 2018

statistical variables. However, for ordered categorical variables almost no literature concerning skewness exists, although this … categorical variables have to be invariant with respect to the group of strictly increasing, continuous transformations. Therefore … type of variables is common for behavioral, educational, and social sciences. Suitable measures of skewness for ordered …

Studying the dependence between ordinal-nominal categorical variables via orthogonal polynomials

Lombardo, Rosaria; Beh, Eric; D'Ambra, Antonello - In: Journal of Applied Statistics 38 (2011) 10, pp. 2119-2132

In situations where the structure of one of the variables of a contingency table is ordered recent theory involving the augmentation of singular vectors and orthogonal polynomials has shown to be applicable for performing symmetric and non-symmetric correspondence analysis. Such an approach has...
