In the anovan function, there seems to be no way of specifying whether the data is dependent across one of the factors, i.e. whether each of these factors is a within- or a between-subjects factor. It is of course essential to know whether different levels of a factor implies values obtained from the same subject ("within-subjects" factor), or from different subjects ("between subjects factor"). The lack of even the terms within- & between-subjects in the entire documentation of this function seems very strange, since this distinction is made in most stats textbooks.
Also, if a significant interaction is reported by this analysis, how does one then use the same anovan function (or a different one in Matlab) to decompose the interaction and make comparisons, for each level of one factor, between the levels of the remaining factor?
Finally, how can I obtain measures of effect size corresponding to a certain comparison, such as omnibus contrast between all levels of a factor, or a pairwise contrast between two specific levels?
Thanks for any help!
