…When assuming a specific population distribution, the parameters of the distribution are the parameters. There are various types of distribution parameters, such as the location parameter that specifies the location, the scale parameter that specifies the scale, and the shape parameter that specifies the shape. For example, in the distribution function of the Weibull distribution, F ( t )=1-exp[-{( t -γ)/η} m ], which is often used in life data analysis, γ, η, and m are the location, scale, and shape parameters, respectively. … *Some of the terminology explanations that mention "location parameter" are listed below.

…特定の母集団分布を仮定する場合には分布のパラメーターが母数である。分布のパラメーターには位置を規定する位置母数,尺度を規定する尺度母数および形状を規定する形状母数などの種類がある。例として寿命データ解析によく用いられるワイブル分布の分布関数, F(t)=1-exp[-{(t-γ)/η}m]において,γ,η,mがそれぞれ位置,尺度,形状母数である。… ※「位置母数」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 |
