From Brown’s biological observation to mathematical Brownian motion 2. Time series observed in the real worl… 190 <iframe src="https://hatenablog-parts.com/embed?url=https%3A%2F%2Fchaos-r.hatenadiary.jp%2Fentry%2F2026%2F01%2F27%2F230252" title="Fractal Fluctuations Between Ideal Theory and Reality — Brownian Motion and Fractional Brownian Motion - 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/20260127/20260127222720.gif Hatena Blog https://hatena.blog 2026-01-27 23:02:52 rich https://chaos-r.hatenadiary.jp/entry/2026/01/27/230252 1.0 100%
