Wavelet coherence analysis suggests that investors do not get any advantages of portfolio diversification investing only in US treasuries with different maturities for more than 256 days and do not get any advantages at all investing only in European bonds.....
Wavelet coherence analysis: a new approach to distinguish organic and functional tremor typesWavelet coherence analysisOBJECTIVE: To distinguish tremor subtypes using wavelet coherence analysis (WCA). WCA enables to detect variations in coherence and phase difference between two signals over time and might...
The wavelet coherence technique allows us to investigate both the long-run and short-term causal relationships between urbanization and environmental sustainability within the global framework. The findings reveal that (i) wavelet correlation from the global perspectives indicates a significant wavelet ...

COVID-19BitcoinWaveletSafe havenWe apply wavelet methods to daily data of COVID-19 world deaths and daily Bitcoin prices from 31th December 2019 to 29th April 2020. We find, especially for the period post April 5, that levels of COVID-19 caused a rise in Bitcoin prices. We contribute to...
Wavelet coherence analysis There are many cerebral oscillations in frequency ranges (except for those below 0.08) that affect hemodynamic fluctuations. By using the WC analysis, the FCs of the somatosensory and motor cortices were calculated in the frequency range up to 4.5 Hz. This upper bound...
This study aims to revisit the evidence of co-movement and lead-lag nexus between carbon dioxide emissions and economic growth in G7 countries over a period of two centuries by using the wavelet coherence analysis. The key findings reveal (i) a cyclical relationship between carbon dioxide emissio...
The wavelet coherence analysis suggests that rising COVID-19 cases in the US have a strong impact on both bank indices. Also, global COVID-19 cases influence the bank indices, although it is not as strong as US COVID-19 cases. Additionally, we have found that the US economic policy ...
(2) wavelet coherence analysis. Bandpass filtering has also been applied. The most significant signature of the solar/geomagnetic forcing in the climate variables was obtained for the data smoothed by the bandpass filter. According to our results, significant solar/geomagnetic forcing appears in the ...
