Forecasting Related Time Series
ABSTRACT A collection of time series are “related” if they follow similar stochastic processes and/or they are statistically dependent. This paper proposes a related time series (RTS) forecasting model that exploits these relationships. The model's foundation is a set of univariate Gaussian autoregressions, one for each series, which are then augmented

A multivariate generalized independent factor GARCH model with an application to financial stock returns [PDF]
We propose a new multivariate factor GARCH model, the GICA-GARCH model , where the data are assumed to be generated by a set of independent components (ICs).

How Tether Depegging Affects Cryptocurrency Returns
ABSTRACT This paper examines the relationship between Tether depegging events and the returns of ten major cryptocurrencies from November 2017 to November 2024. We distinguish between upward and downward deviations from the Tether peg, identifying these events as threshold exceedances based on historical prices, using both constant parameter and ...

Forecasting Stock Market Volatility Using CNN-BiLSTM-Attention Model with Mixed-Frequency Data
Existing stock volatility forecasting models predominantly rely on same-frequency market data while neglecting mixed-frequency integration and face particular challenges in incorporating low-frequency macroeconomic variables that exhibit temporal ...

How Regulation and Global Standing Shape Stock Market Co‐Movements: A G20 Panel Study
ABSTRACT Motivated by post‐2020 fragmentation and underexplored institutional‐geopolitical drivers, we examine how regulatory quality (RQ) and global power (GP) shape stock‐market co‐movements across 17 G20 economies. We estimate time‐varying correlations via ADCC‐GARCH, construct a scaled correlation index, and apply panel ARDL. We find that higher RQ

Day-of-the-week effect on the Tunisian stock market return and volatility
In this paper, we examine empirically the day-of-the-week effect on the Tunisian stock exchange index (TUNINDEX) return and volatility. We use three multivariate general autoregressive conditional heteroscedasticity models (GARCH (1,1), EGARCH (1,1), and

Parametric Model Order Reduction by Box Clustering With Applications in Mechatronic Systems
ABSTRACT High temperatures and structural deformations can compromise the functionality and reliability of new components for mechatronic systems. Therefore, high‐fidelity simulations (HFS) are employed during the design process, as they enable a detailed analysis of the thermal and structural behavior of the system.
