A study of instantaneous emissions through the decomposition of directional measures for three-way contingency tables with ordered categories

The aim of this study is to evaluate the Nitrogen Oxides (NOx) emissions trough an accurate analysis of vehicle driving behaviour. For this purpose, a three-way contingency table will be carried out, crossing the NOx emissions, the speed and the acceleration. This contingency table will be analysed by the partition of Marcotorchino index. To complement the survey Ordered Non-Symmetric Correspondence Analysis (ONSCA) will be applied.
