The concordance probability, also called the C-index, is a popular measure to capture discriminatory ability of predictive model. In this article, definition adapted specific needs frequency and severity model, typically used during technical pricing non-life insurance product. For need two different groups tackled by defining three new types probability. Secondly, these definitions deal with c...

This article aims to provide a more comprehensive analysis of the investor’s behaviour. To do so, we first address concept individual behaviour which lacks rigorous, precise definition that would be unanimously accepted. The multidimensional nature and complexity human are approached from both psychological financial point view, by examining its relationship with genetic structure, psychic stru...

In the paper by Fan (Inf Dim Anal Quant Probab Rel Topics 9:451–469, 2006), he introduced marginal selfsimilarity of non-commutative stochastic processes and proved that distributions selfsimilar with freely independent increments are selfdecomposable. this paper, we firstly introduce a new definition, stronger than Fan’s in general, via linear combinations processes, although two definitions e...

By making use of the purpose definition set out by British Academy�s Future Corporation programme we argue that performance relates to in two dimensions. Firstly, sets frame long-term success and defines materiality for an organisation both from a single double perspective. Secondly, relation needs measure profitability net negative externalities. We review discuss current landscape non-financi...

Abstract The aim of this article is to illustrate some key points that will hopefully encourage further reflection on the cinematic representations and meanings populism in both an Italian international context. Firstly, we attempt a definition as applied cinema, drawing political science literature film history. Secondly, turn critics directors, discussing views them hold relation cinema recen...

Searching for novel signal processing theories and methods has always been a research hotspot in the field of modern processing. The existing transform dealing with non-stationary signals are based on traditional Cartesian coordinates, which very inconvenient to deal naturally described by polar coordinates. This paper studies two-dimensional offset linear canonical (OLCT) Firstly, definition O...

The article analyzes two moments that mark the construction of schistosomiasis as a public health problem in Brazil. First, 1910s, controversies surrounding definitions disease involved Bahian physician Pirajá da Silva, character dispute with international circles medical-scientific production. Secondly, mobilizations 1950s, when entered mass diseases agenda Brazilian developmental political pr...

This paper examines the recursive definition of an increasing sequence of nested sets by means of a control set whose countably many successive redefinitions leads to a contradictory result that compromises ω-order and the Axiom of Infinity. 1. Recursion and successiveness A recursive definition usually starts with a first definition (basic clause) which is followed by an infinite (usually ω-or...

With databases growing at an unrelenting rate, it may be difficult and complex to extract statistics by accessing all of the data in many practical problems. Attribute reduction, as effective method remove redundant attributes from massive data, has demonstrated its remarkable capability simplifying information systems. In this paper, we concentrate on reducing incomplete We introduce a novel d...
