Modeling Markov switching ARMA-GARCH neural networks models and an application to forecasting stock returns. [PDF]
ScientificWorldJournal, 2014 The study has two aims. The first aim is to propose a family of nonlinear GARCH models that incorporate fractional integration and asymmetric power properties to MS‐GARCH processes. The second purpose of the study is to augment the MS‐GARCH type models with artificial neural networks to benefit from the universal approximation properties to achieve ...

A Study of Nigeria Monthly Stock Price Index Using ARTFIMA-FIGARCH Hybrid Model
UMYU Scientifica Journal, 2023 Long memory is a phenomenon in time series analysis that is exhibited by a slow decay of the autocorrelation function. It has been observed that the presence of long memory in both mean and volatility can complicate model fitting and compromise ...

Direct versus iterated multiperiod Value‐at‐Risk forecasts
Journal of Economic Surveys, Volume 37, Issue 3, Page 915-949, July 2023., 2023 Abstract Since the late nineties, the Basel Accords require financial institutions to measure their financial risk by reporting daily predictions of Value at Risk (VaR) based on 10‐day returns. However, a vast part of the related literature deals with VaR predictions based on one‐period returns.

Estimating the volatility of asset pricing factors
Journal of Forecasting, Volume 40, Issue 2, Page 269-278, March 2021., 2021 Abstract Models based on factors such as size or value are ubiquitous in asset pricing. Therefore, portfolio allocation and risk management require estimates of the volatility of these factors. While realized volatility has become a standard tool for liquid assets, this measure is difficult to obtain for asset pricing factors such as size and value ...

Do Scarce Precious Metals Equate to Safe Harbor Investments? The Case of Platinum and Palladium
Economics Research International, Volume 2016, Issue 1, 2016., 2016 This research establishes the predictability and safe harbor properties of two scarce precious metals, namely, platinum and palladium. Utilizing their spot prices, the study concludes intermediate memory in the return structures of both precious metals, which implies the instability of platinum and palladium returns’ persistency in the long run ...

Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015 The establishment of electrical power system cannot only benefit the reasonable distribution and management in energy resources, but also satisfy the increasing demand for electricity. The electrical power system construction is often a pivotal part in the national and regional economic development plan.

International Scholarly Research Notices, Volume 2014, Issue 1, 2014., 2014 The mass and energy‐capital conservation equations are employed to study the time evolution of mass and price of nonrenewable energy resources, extracted and sold to the market, in case of no‐accumulation and no‐depletion, that is, when the resources are extracted and sold to the market at the same mass flow rate.
