In this paper we discuss the basic procedures for the implementation of multivariate statistical process control via control charting. Furthermore, we review multivariate extensions for all kinds of univariate control charts, such as multivariate Shewhart-type control charts, multivariate CUSUM...

We use Confirmatory Factor Analysis (CFA) to derive a unifying measure of comparison of scientists based on bibliometric measurements, by utilizing the h-index, some similar h-type indices as well as other common measures of scientific performance. We use a real data example from nine well-known...

In this paper, some new indices for ordinal data are introduced. These indices have been developed so as to measure the degree of concentration on the "small" or the "large" values of a variable whose level of measurement is ordinal. Their advantage in relation to other approached is that they...
