請問統計分析方法RM-ANOVA

如題

請問repeated measures analyses of variance(RM-ANOVA)

是怎樣的一個統計分析方法?

我在網路上蒐尋找不到我看得懂得解釋或是介紹.

所以在此請教大家.

用簡單的說明就可以了.

謝謝!

    一般最常用的ANOVA大多只比較不同組別在1個依變項的差異,

    若有前、後測的時候,可以用ANCOVA(共變數分析),將前測視為共變數予以控制,

    但若有3個以上的測量,此時就要選用repeated measures(重覆量數)ANOVA。

    可參考SAS軟體網路上的說明:

    When several measurements are taken on the same experimental unit (person, plant, machine, and so on), the measurements tend to be correlated with each other.

    當測量是相同的實驗單位(人,植物,機器,等等) ,測量間傾向於彼此相關。

    When the measurements represent qualitatively different things, such as weight, length, and width, this correlation is best taken into account by use of multivariate methods, such as multivariate analysis of variance.

    當測量代表描述不同的事情時,如重量,長度和寬度等,因為使用多變量方法所以能考慮這相互關係,例如多變量分析

    When the measurements can be thought of as responses to levels of an experimental factor of interest, such as time, treatment, or dose, the correlation can be taken into account by performing a repeated measures analysis of variance.

    當我們認為測量可以是對各水準一個所關心的實驗因素的回應時, 例如時間,處理,或者劑量,透過重複測量變化的分析執行可以考慮到相互關係。
