Evaluation of Dual Long Memory Properties with Emphasizing the Skewed and Fat-Tail Distribution: Evidence from Tehran Stock Exchange [PDF]
Muṭāli̒āt-i Mudīriyyat-i Ṣan̒atī, 2014 This paper investigates the presence of long memory in the Tehran stock market, using the ARFIMA, GPH, GSP and FIGARCH models. The data set consists of daily returns, and long memory tests are carried out both for the returns and volatilities of TEPIX ...

A note on asymptotic inference for FIGARCH($p, d, q$) models [PDF]
Statistics and Its Interface, 2011 Parameters estimation for a FIGARCH(p, d, q )m odel is studied in this paper. By constructing a compact parameter space Θ satisfying the non-negativity constraints for the FI- GARCH model, it is shown that the results of Robinson and Zaffaroni (2006) can be applied to establish the strong con- sistency and asymptotic normality of the quasi-maximum ...

Stochastic equilibrium of free trade under a FIGARCH volatility
, 2023 Abstract Free trade for some economists gains so much attention, the horrible thing is though when a nation doesn't knit relations with other countries because this would harm the future gains almost if land or property is rare: what i had tried to mention is the importance of free trade as far as consumption is concerned, if the national ...

A Hybrid LSTM Neural Network Approach for Modeling Periodical Long-Memory Characteristics in Financial Energy Index Time Series [PDF]
Mathematics and Modeling in FinanceForecasting financial market volatility has always been a major challenge in economics and financial engineering. In this study, a hybrid approach based on FIGARCH and PLM-GARCH models combined with Long Short-Term Memory (LSTM) neural networks is ...

Parametric Time‐Variation in the Unconditional Volatility: Estimation and Inference
Journal of Time Series Analysis, EarlyView.ABSTRACT We propose modeling time‐variation in the unconditional volatility by augmenting the standard GARCH model by a deterministic time‐varying intercept. The model, called the additive time‐varying (ATV‐)GARCH model, can be interpreted as a reduced form of a model including covariates and can be derived from a multiplicative decomposition of ...
