15.126 14.5.17 Agregación por fase

15.126.1 Ventanas

Boundary-centered, PhaseInterval, MoveEpisode, Attempt, SlidingWindow, ContactEpisode

15.126.2 Estadísticos

mean, median, SD, MAD, min/max with time, quantiles, integral, path length, duration, curve after phase normalization

15.126.3 Incertidumbre de frontera

• Compute at nominal boundaries plus earliest/latest sensitivity.
• Monte Carlo sample boundary distributions and report feature quantiles.
• Mark feature Censored when window length or valid coverage becomes insufficient.

Validez mínima: Each feature definition/profile declares minimum duration, sample count, coverage and derivative edge margin.

15.126.4 Tiempo normalizado

τ = (t - t_start) / (t_end - t_start),  0 ≤ τ ≤ 1

El remuestreo por fase sirve para comparar la forma de curvas, pero siempre se conserva duración real y frontera original.
