Hi, I am running an ANCOVA model like:
aov(Y ~ Var1 + Var2 + Var3 + Var4 + CoVar1 + CoVar2) where Y is the response (metric, 1.0-1000.0), VarX are all metric predictors, and CoVarX are two Covariates each a factor of 4-5 levels. So far as I can remember results of an ANCOVA for a Covariate of interest (e.g. CoVar1) are given as e.g. (ANCOVA Fx,y = 2.72, P-value = 0.01). But which degrees of freedom (df) are usually reported together with an F-value (x and y?)? Which df do I need to extract from the model resp the model summary? best regards, Johannes ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
