Re: [R] Difference between two-way ANOVA and (two-way) ANCOVA

The usual terminology uses the number of "ways" to mean the number of factors (categorical or classification variables, with more than one degree of freedom per factor). The term covariate is used for continuous variables, with exactly one df. On Wed, Jul 4, 2012 at 9:20 AM, syrvn wrote: > Hi! >

[R] Difference between two-way ANOVA and (two-way) ANCOVA

Hi! as my subject says I am struggling with the different of a two-way ANOVA and a (two-way) ANCOVA. I found the following examples from this webpage: http://www.statmethods.net/stats/anova.html # One Way Anova (Completely Randomized Design) fit <- aov(y ~ A, data=mydataframe) # Randomized Blo
