Aeon Periodograms for Unequal-Length Time Series
How Aeon's PeriodogramTransformer pads unequal-length collections, why its list and 3-D branches need parity, and what one case study teaches.
Fourier Smoothing in Aeon: Symmetry, Cutoffs, and Better Tests
A bounded Aeon DiscreteFourierApproximation case study shows how conjugate symmetry, passband gain, and cutoff semantics expose concrete Fourier failure modes.
Your ACF Can Be Right While Its Confidence Interval Is Wrong
A missing-data bug in statsmodels left ACF estimates unchanged while confidence intervals and Ljung-Box statistics used the wrong sample size.
