تاکنون مدل های مختلفی برای پیش بینی وضعیت ریسک اعتباری و احتمال ورشکستگی مشتریان ارایه شده است. در این میان استفاده از مدلی که تنها متکی بر داده های تاریخی نباشد و از داده های بازار نیز به عنوان هشداری در مورد وضعیت فعلی مشتری و حتی انتظارات نسبت به وضعیت آینده آن باشد، ضروری به نظر می رسد. هدف از این تحقیق به کارگیری مدل کی ام وی جهت پیش بینی ورشکستگی مشتریان حقوقی بانک های ایرانی و ارزیابی دق...
The interest in the prediction of corporate bankruptcy is increasing due to the implications associated with this phenomenon (e.g. economic, and social) for investors, creditors, competitors, government, although this is a classical problem in the financial literature. Two kinds of models are generally adopted for bankruptcy prediction: (i) accounting ratios based models and (ii) market based m...
We consider the modelling of dependent defaults in large credit portfolios using latent variable models (the approach that underlies KMV and CreditMetrics) and mixture models (the approach underlying CreditRisk). We explore the role of copulas in the latent variable framework and show that for given default probabilities of individual obligors the distribution of the number of defaults in the p...
In this paper, we study the relationship between default probability and stock returns. Using the market-based measure of Expected Default Frequency (EDF) constructed by Moody’s KMV, we first demonstrate that higher default probabilities are not necessarily associated with higher expected stock returns, a finding that complements the existing empirical evidence. We then show that the puzzling...
abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...
rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
The situation of a limited availability of historical data is frequently encountered in portfolio risk estimation, especially in credit risk estimation. This makes it, for example, difficult to find temporal structures with statistical significance in the data on the single asset level. By contrast, there is often a broader availability of cross-sectional data, i.e., a large number of assets in...
since its introduction in 1959, translation quality assessment (tqa) has been among the most addressed research topics in translation studies. during recent years, there has been a crucial increase on the study of tqa. various methods have come on scene. although these methods are based on scientific theories, most of them have remained at the level of theory. juliane house’s model is among tho...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
