Wavelet Coherence Analysis

Methodology

Wavelet coherence analysis serves as a powerful signal processing tool for detecting localized similarities between two non-stationary time series across various time-frequency domains. Quantitative analysts utilize this approach to isolate transitory correlations in cryptocurrency markets that standard linear models typically obscure. By decomposing price data and volatility series into specific temporal scales, it captures the evolving coupling between disparate assets or derivatives with granular precision.
