Determination of biochemical methane potential (BMP) by fermentation tests is time-consuming and costly, and therefore not useful for operators of full-scale biogas digesters. A great advantage of NIRS in determining BMP is the reduction in measurement time from at least one month for chemical...

In high-dimensional data, one often seeks a few interesting low-dimensional projections that reveal important features of the data. Projection pursuit is a procedure for searching high-dimensional data for interesting low-dimensional projections via the optimization of a criterion function...

Sustainable development assumes improvement in the quality of living of present and future generations by achieving social, economic and environmental balance. Demographic changes play a significant role in this process due to their long-term impact on social and economic outcomes. The...

The methods of analysis of acquired information from marketing researches must respond to the market environment. One of these methods which may be used is Conjoint Analysis. Conjoint Analysis allows: to denote how big the total efficiency of product (service) of particular quality represents...

The aim of this paper is to give an overview of three important techniques; factor, cluster and discriminant analysis. I find it necessary and more important to have an understanding of the basic assumptions and the underlying foundations of the methods rather than a thorough mathematical...
