In statistics and in particular in regression analysis, a design matrix, also known as model matrix or regressor matrix and often denoted by X, is a matrix of values of explanatory variables of a set of objects. Each row represents an individual object, with the successive columns corresponding to the variables and their specific values for that object. The design matrix is used in certain statistical models, e.g., the general linear model. It can contain indicator variables (ones and zeros) that indicate group membership in an ANOVA, or it can contain values of continuous variables.

  • 計画行列(けいかくぎょうれつ、英: design matrix)とは、統計学において、いくつかの統計モデル、たとえば一般化線形モデルで用いられる行列である。 指示変数 (indicator variable) を含むことがある。指示変数は1かゼロの値をとり、グループに帰属するか否かを示す。 計画行列の利点は、多種類の実験計画や統計モデルを表現できることである。たとえば分散分析や共分散分析、線形回帰などである。 (ja)

  • In der Statistik ist die Datenmatrix, auch Versuchsplanmatrix, Designmatrix (von englisch research design: deutsch Versuchsplan), Modellmatrix, Beobachtungsmatrix oder Regressormatrix genannt, eine Matrix, die Daten über mehrere Merkmale mehrerer Personen oder Objekte (statistische Einheiten) enthält. Sie ist Grundlage des klassischen Modells der linearen Mehrfachregression. Der Begriff Versuchsplan- bzw. Designmatrix (bezeichnet mit ) kommt aus dem Teilgebiet der statistischen Versuchsplanung, die sich mit dem statistisch optimalen Entwurf von Experimenten beschäftigt (siehe Optimale Versuchsplanung). Wenn die Werte der geplant sind (vom Forscher festgelegt), enthält die -Matrix im Wesentlichen den Versuchsplan und wird daher manchmal als Versuchsplanmatrix bezeichnet. (de)
  • In statistics and in particular in regression analysis, a design matrix, also known as model matrix or regressor matrix and often denoted by X, is a matrix of values of explanatory variables of a set of objects. Each row represents an individual object, with the successive columns corresponding to the variables and their specific values for that object. The design matrix is used in certain statistical models, e.g., the general linear model. It can contain indicator variables (ones and zeros) that indicate group membership in an ANOVA, or it can contain values of continuous variables. The design matrix contains data on the independent variables (also called explanatory variables) in statistical models which attempt to explain observed data on a response variable (often called a dependent variable) in terms of the explanatory variables. The theory relating to such models makes substantial use of matrix manipulations involving the design matrix: see for example linear regression. A notable feature of the concept of a design matrix is that it is able to represent a number of different experimental designs and statistical models, e.g., ANOVA, ANCOVA, and linear regression. (en)
