Such two-dimensional trajectories arise naturally in many experimental and observational settings, particularly in the analysis of biological signals. Typical examples include fluctuations of t… 190 <iframe src="https://hatenablog-parts.com/embed?url=https%3A%2F%2Fchaos-r.hatenadiary.jp%2Fentry%2F2026%2F01%2F30%2F013552" title="Oriented Fractal Scaling Component Analysis (OFSCA): Detection and Decomposition of Direction-Specific Fractal Fluctuations - Ken-Chaos’s Random Notes on R" class="embed-card embed-blogcard" scrolling="no" frameborder="0" style="display: block; width: 100%; height: 190px; max-width: 500px; margin: 10px 0px;"></iframe> https://cdn-ak.f.st-hatena.com/images/fotolife/c/chaos_kiyono/20260130/20260130005925.png Hatena Blog https://hatena.blog 2026-01-30 01:35:52 rich https://chaos-r.hatenadiary.jp/entry/2026/01/30/013552 1.0 100%
