Prediction in financial domains is notoriously difficult for a number of reasons. First, theories tend to be weak or non-existent, which makes problem formulation open ended by forcing us to consider a large number of independent variables and thereby increasing the dimensionality of the search space. Second, the weak relationships among variables tend to be nonlinear, and may hold only in limi...

There are basically six functional associated with credit lending activities of banks in general: (1) assessment of the customers credit risk; (2) making the credit granting decision; (3) collecting debts; ...

In this paper it is argued that Hintikka’s game theoretical semantics for Independence Friendly logic does not formalize the intuitions about independent choices; it rather is a formalization of imperfect information. Furthermore it is shown that the logic has several strange properties (e.g. renaming of bound variables is not allowed). An alternative semantics is proposed which formalizes intu...

Several variants of a first-order simplification rule for nonnormal form tableaux using syntactic constraints are presented. These can be used as a framework for porting methods like unit resolution or hyper tableaux to non-normal form free variable tableaux.

An alternative approach to the semantics of definite descriptions was proposed by Heim in her dissertation [1982]. Heim assigns to pragmatics a larger part of the task of specifying the meaning of definite descriptions than the neo-Russellians do. In Heim’s theory, definite and indefinite NPs are semantically equivalent, and both introduce free variables. The truth conditions proposed by Heim f...

The purpose of this study is presenting a model forecasting financial crisis in Tehran Stock Exchange listed companies. To do this, productive firms that had been accepted in Tehran Stock Exchange between 2002 and 2009, were selected as the study sample. First the independent variables were obtained based on financial ratios and then based on Article 141 of the Law of Commerce, the insolvent an...
