Signal Interpretation in Hotelling’s T 2 Control Chart for Compositional Data
Nowadays, control of concentrations of elements is of crucial importance in industry. Concentrations are expressed in terms of proportions or percentages which means that they are compositional data (CoDa). CoDa are defined as vectors of positive elements that represent parts of a whole and usually add to a constant sum. Classical T 2 control chart is not appropriate for CoDa, for which is bett...
متن کاملCompositional Synthesis of Reactive Systems from Live Sequence Chart Specifications
Synthesis is the process of automatically generating a correct running system from its specification. In this paper, we suggest a translation of a Live Sequence Chart specification into a two-player game for the purpose of synthesis. We use this representation for synthesizing a reactive system, and introduce a novel algorithm for composing two such systems for two subsets of a specification. E...
متن کاملRobust Methods for Compositional Data
Abstract. Many practical data sets in environmental sciences, official statistics and various other disciplines are in fact compositional data because only the ratios between the variables are informative. Compositional data are represented in the Aitchison geometry on the simplex, and for applying statistical methods designed for the Euclidean geometry they need to be transformed first. The is...
متن کاملCorrelation Analysis for Compositional Data
Compositional data need a special treatment prior to correlation analysis. In this paper we argue why standard transformations for compositional data are not suitable for computing correlations, and why the use of raw or log-transformed data is neither meaningful. As a solution, a procedure based on balances is outlined, leading to sensible correlation measures. The construction of the balances...
متن کاملHaptic Interaction Techniques for Exploring Chart Data
Haptic data visualization is a growing research area. It conveys information using the sense of touch which can help visually impaired people or be useful when other modalities are not available. However, as haptic devices and virtual worlds exhibit many challenges, the haptic interactions developed are often simple and limited to navigation tasks, preferring other modalities to relay detailed ...
