Quadratic variation is just one kind of variation of a process. == Definition == Suppose that ''X''''t'' is a real-valued stochastic process defined on a probability space $(\backslash Omega,\backslash mathcal,\backslash mathbb)$ and with time index ''t'' ranging over the non-negative real numbers. Its quadratic variation is the process, written as ()''t'', defined as :$()\_t=\backslash lim\_\backslash sum\_^n(X\_-X\_\backslash sum\_^\backslash left(X\_-X\_-Y\_(()\_t-()\_t).$ 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Quadratic variation」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
