Question

Quizplus · Accepted Answer

The aov command from the "stats" package in R's System Library was used for ANOVA and ANCOVA and the manova command, also from the "stats" package, was used for MANOVA and MANCOVA. Answer A is incorrect because there is no "anova" package (there is an "Anova" package but it was only mentioned, not used, in the text). Answer B is incorrect for the same reason. Answer D is in error also: the glm command was used for logistic regression.
