A new kind of entropy will be introduced generalizing both the differential entropy and the cumulative (residual) entropy. The generalization is twofold. Firstly, we define the entropy for cumulative distribution functions (cdf) and survivor functions (sf) simultaneously instead of densities,...

Early attempts to develop a modern model for the assessment of performance of portfolios of instruments belong to American teacher Harry Markowitz. He has abandoned the classical approach of the analysis of financial investment (based solely on technical and fundamental analysis), pointing...

Within financial theory and practice, there are used five main criteria for selecting investment projects: the net present value (NPV) criterion, the internal rate of return (IRR) criterion, the return term (RT) criterion, the profitability ratio (PR) criterion and the supplementary return (SR)...

This paper describes a method for getting a synthesis of the knowledge about a given system, assuming that a data set x of measurements of a variable Ξ is known: i.e., separate data are combined in order to form a coherent whole, à la thermodynamics. For getting the macroscopic...
