The purpose of the paper is to discuss ten things potential users should know about the limits of the Dynamic Conditional Correlation (DCC) representation for estimating and forecasting time-varying conditional correlations. The reasons given for caution about the use of DCC include the following: DCC represents the dynamic conditional covariances of the standardized residuals, and hence does n...

در این مقاله اثر شوک‌های نرخ ارز را در تلاطم شاخص فلزات اساسی لحاظ کرده و برای مدل‌سازی آن از یک مدل ARJI-GARCH استفاده می‌کنیم. به این منظور ابتدا از مدل شدت جهش شرطی خودبرگشت (ARJI) برای مدل‌سازی تلاطم نرخ ارز استفاده می‌کنیم، سپس نتیجة آن را برای برآورد تلاطم شاخص صنعت فلزات اساسی در یک مدل GARCH به کار می‌بریم. در ادامه از تلاطم برآورد شده با مدل ARJI-GARCH ارزش در معرض ریسک (VaR) شاخص فلز...
این تحقیق درصدد یافتن جزئیات رابطه بین بازارهای نفت خام و بازارهای سهام کشورهای صادرکننده و واردکننده نفت می باشد. داده های روزانه شامل قیمت های نقد wti و brent و قیمت های آتی های یک تا چهار ماهه wti و شاخص های قیمت و قیمت و بازده نقدی کشور ایران و شاخص های قیمت و بازده کشور ترکیه بوده؛ که دامنه داده ها از ابتدای سال 2000 تا انتهای سال 2010 و مشتمل بر 1408 داده مشترک به ازای همه بازارها می باشد...

Deleted in colorectal cancer (DCC) is a candidate tumor-suppressor gene located at chromosome 18q21. However, DCC gene was found to have few somatic mutations and the heterozygous mice (DCC(+/-)) showed a similar frequency of tumor formation compared with the wild-type mice (DCC(+/+)). Recently, DCC came back to the spotlight as a better understating of its function and relationship with its li...
Empirical studies show that there is stronger dependency between large losses than large profit in financial market, which undermine the performance of using symmetric distribution for modeling these asymmetric. That is why the assuming normal joint distribution of returns is not suitable because of considering the linier dependence, and can be lead to inappropriate estimate of VaR. Copula theo...
the efficiency and robustness of reliability methods are two important factors in first order reliability method (form). the conjugate choice control (ccc) and directional chaos control method (dcc) were developed to improve the robustness and efficiency of form formula using the stability transformation method. in this paper, the ccc and dcc methods are applied for reliability analysis of a co...
