Reinforcing measurement scale for ordinal data in multivariate statistical analysis

Summary/Abstract: The data matrix is the starting point for the application of multivariate statistical methods. The problem of application of multivariate statistical analysis methods becomes more complicated when the variables in data set are measured on mixed scales or contain variables measured on weak measurement scales only (especially on ordinal scale). In the article we propose a method of reinforcing measurement scale for ordinal data. The proposal is based on GDM2 distance for ordinal data. Considered aspects are illustrated by empirical example and R program.
