… In response to the above, AN Kolmogorov, N. Wiener, and others have developed a mathematical theory that aims to analyze yt by calling yt in the formula xt = mt + yt the disturbance or error and assuming that mt is constant. In reality, it is necessary to construct a model from the observed time series, and for this purpose , autoregressive models and moving average models in particular have been studied. Autoregression (autoregression)… *Some of the terminology explanations that mention the "moving average model" are listed below. Source | Heibonsha World Encyclopedia 2nd Edition | Information |
… 以上に対し,xt=mt+ytの式のytをかく乱あるいは誤差と呼んで,mtは一定と考えた上でytを分析することを目的とする数学的理論が,A.N.コルモゴロフ,N.ウィーナーなどによって発展されている。現実には,観測される時系列からモデルを構築する必要があり,そのためには特に自己回帰モデルと移動平均モデルが研究されている。自己回帰(auto‐regression。… ※「移動平均モデル」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
