Reading the documentation for Matlab's repeated-measures ANOVA, I noticed two things that didn't make sense to me (I am reasonably literate in statistics):
1) In this example (the fisheriris dataset), "species" is taken as the predictor variable - however species is a between-subjects factor, not within-subjects! 2) The output of another example for a repeated measures ANOVA lists Group as a within-subjects factor when it too is clearly between-groups.
Also, why is it that all factors' names in that output table end in "time", e.g. "Group:Time"? Is that because most repeated measures are normally measurements done across time? This is really confusing.
Thanks for any help clarifying these points!
