What It Is
MotionSense smartphone accelerometer magnitude during walking. 50 Hz triaxial IMU collapsed to vector norm; ~2 Hz gait cycle.
Interpretation
Standard analysis sees: heavy-tailed; right-skewed. The atlas finds no named structure, but the source is distinctively extreme on Nonstationarity:regime_persistence (+4.7z) — beyond what the standard bank predicts for it. It sits beside Wind Speed in the atlas (standard-bank rank 28) — a neighbor conventional features miss.
