What It Is
Driven damped nonlinear oscillator --- strange attractor with broad amplitude visits
Interpretation
Standard analysis sees: smooth / autocorrelated; long-range memory (persistent); low-complexity (predictable, not noise-like); volatility-clustering (bursty). The atlas additionally detects Nonstationarity:adf_pvalue.
