安德森鳶尾花卉數據集

安德森鳶尾花卉數據集英文Anderson's Iris data set),也稱鳶尾花卉數據集英文Iris flower data set)或費雪鳶尾花卉數據集英文Fisher's Iris data set),是一種多重變數分析數據集。它最初是埃德加·安德森從加拿大加斯帕半島鳶尾屬花朵中提取的形態學變異數據[1],後由羅納德·費雪作為判別分析的一個例子[2],運用到統計學中。

其數據集包含了150個樣本,都屬於鳶尾屬下的3個亞屬,分別是山鳶尾變色鳶尾維吉尼亞鳶尾英語Virginia Iris。每個樣本都包含4項特徵,即花萼花瓣的長度和寬度,它們可用於樣本的定量分析。基於這些特徵,費雪發展了能夠確定其屬種的線性判別分析
