Causality Analysis for COVID-19 among Countries Using Effective Transfer Entropy
Ünal, Baki (MDPI, 2022)In this study, causalities of COVID-19 across a group of seventy countries are analyzed with effective transfer entropy. To reveal the causalities, a weighted directed network is constructed. In this network, the weights ... -
Intraday Seasonality and Volatility Pattern: An Explanation with Recurrence Quantification Analysis
Ünal, Baki; Küçükkocaoğlu, Güray; Kadıoğlu, Eyüp (World Scientific, 2023)The Recurrence Quantification Analysis (RQA), a pattern recognition-based time series analysis method, can be successfully utilized for short, nonstationary, nonlinear, and chaotic time series. These RQA measures quantify ... -
Nonlinear and Chaotic Time Series Analysis
Ünal, Baki; Aladağ, Çağdaş Hakan (World Scientific Publishing Co., 2022)This study introduces the techniques used in the analysis of nonlinear and deterministic time series. Since chaotic time series are nonlinear and deterministic, the techniques introduced here can be successfully applied ... -
Stability Analysis of Bitcoin using Recurrence Quantification Analysis
Ünal, Baki (Chaos Theory and Applications, 2022)Cryptocurrencies are new kinds of electronic currencies based on communication technologies. These currencies have attracted the attention of investors. However, cryptocurrencies are very volatile and unpredictable. For ... -
Terrestrial biosphere water balance analysis: a mathematical model to predict the impacts of climate change on net water budget on global scale
Sakallı, Abdulla; Ünal, Baki (Corvinus University of Budapest, 2023)The industrial revolution triggered increased greenhouse gas emissions, disrupting the water cycle, and raising global temperatures by 2°C. This shift has induced extreme weather, rising sea levels, altered precipitation, ...
