ST 512 Week 12 Notes MaLyn Lawhorn October 30, 2017 and November 1, 2017 Analysis of Covariance Model (ANCOVA) An ANCOVA model is one in which the experimental and confounding factors do not interact. We have three different categories of terms in the model ▯ Y -response variable ▯ X ;1▯▯ ;X -erperimental factors ▯ Z 1▯▯▯ ;Z -csnfounding factors The model itself is of the form iid 2 Y = ▯ (e ;x1;▯▯2 ;x ) + r (z ;zc;▯1▯ 2z ) + E s E ▯ (0;▯ ): We use the ANCOVA model as opposed to the one-way model when there are factors that are un- related to the experimental variables.
