Five standard diagnostic categories (N, S, V, Q, and F) were considered. A comparative framework was developed, including a standalone 1D-CNN model and three hybrid models based on different HHT-derived features. Model performance was assessed …

Combined Hybrid Ardl-Garch-Bigru Model In Analyzing And Forecasting Currency In Circulation Issued By The Central Bank Of Iraq, Abdulrazzaq Tallal Akram, Omar Abdulmohsin Ali

Journal of Economics and Administrative Sciences

This research examines the dynamics and forecasting performance of currency in circulation (CIC) in Iraq. It uses a theoretical framework that recognizes long-run equilibrium relationships, short-run adjustment, volatility clustering, and nonlinear patterns. These complexities limit the adequacy of traditional linear models and motivate hybrid approaches. Accordingly, a triple hybrid model is employed. This combines autoregressive distributed lag (ARDL), Generalized Autoregressive Conditional Heteroskedasticity (GARCH) with Generalized Error Distribution (GED) to capture heavy-tailed behavior, and Bidirectional Gated Recurrent Unit (BIGRU). Stationarity is assessed using ADF tests. Residual diagnostic tests confirm heteroskedasticity, thereby justifying the inclusion of a GARCH component. The proposed model …

An Improved Logarithmic Ratio-Product Type Estimator For Mean Modeling And Estimation Under Neutrosophic Uncertainty, Anchal Yadav, Mukesh Kumar

Neutrosophic Systems with Applications

In classical statistics, population mean estimation generally assumes precise and determinate data along with known auxiliary information. However, in real-world situations where observations are imprecise or expressed in interval form, such as temperature variations or financial market data, classical approaches become less effective. To address this limitation, neutrosophic statistics provide a more flexible framework for handling uncertainty and indeterminacy. This study proposes a neutrosophic logarithmic ratio-product type estimator for estimating the finite population mean using auxiliary information. The bias and mean squared error (MSE) of the proposed estimator are derived using a first-order approximation. Furthermore, performance evaluation is carried out …

Uncertainty Handling In Stock Market Prediction: A Fuzzy Markov Chain Approach, Alpa Singh Rajput, Arpan Singh Rajput

Neutrosophic Systems with Applications

Predicting the stock market is never easy because it is influenced by many uncertain and constantly changing factors such as economic conditions, investor behaviour, and global events. Traditional models like the Crisp Markov Chain (CMC) try to predict market movements by using fixed probabilities for different states like bullish, bearish, or stagnant. However, real markets do not behave in such a strict way—they often move gradually between states, which these models fail to capture. To overcome this limitation, this study introduces a Fuzzy Markov Chain (FMC) model, where fuzzy logic is used to handle uncertainty and allow smoother transitions between …
