CategoricalValue

CategoricalValue[cat]

カテゴリオブジェクト cat のもとになっている式を与える．

CategoricalValue[scale]

与えられたカテゴリ尺度 scale のカテゴリに関連付けられた式を与える．

CategoricalValue[obj,prop]

カテゴリまたはカテゴリ尺度について指定された特性 prop を与える．

詳細

  • CategoricalValueは，通常，名義カテゴリまたは順序カテゴリおよびそれらの尺度から特性を取得するために用いられ，とりわけそれらのもとになっている式を抽出するために用いられる．
  • CategoricalValueの第1引数は，単一のカテゴリを表す場合にもカテゴリ尺度を表す場合にも，NominalオブジェクトまたはOrdinalオブジェクトのいずれかとすることができる．CategoricalValueはリスト入力に対して縫い込まれる．
  • 使用可能な特性 prop には以下がある．
  • "Expression"カテゴリのもとになっている式
    "Category"個々のNominalカテゴリまたはOrdinalカテゴリ
    "CategoryCode"可能な尺度のインデックス値
    "Label"カテゴリのタイプセットに使用されるラベル
    "Scale"カテゴリカルなスケール
    "Score"Ordinalにおける並べ替えに使用される数値スコア
  • CategoricalValue[obj]はCategoricalValue[obj,"Expression"]に等しい．
