I would like to make an anova on several factors
Is there a simple example available?
best regards

We currently support only onefactor ANOVA. We have plans to support twofactor ANOVA ( https://metanumerics.codeplex.com/workitem/4607) but as you can read in those bug notes,
the correct analysis for unbalanced designs is debatable. I do intend to eventually go back to this question, and I will count your request as a vote for that feature.
I'd like to ask a few followup questions if I may. (1) How many factors do you intend to simultaneously analyze? (2) Is your design balanced, i.e. equal numbers of entries in each variant of each factor? (3) Are you sure ANOVA is appropriate to your question,
i.e. factors variants really are discrete and unordered (e.g. Continent of origin = {America, Europe, Asia, Africa} not Dose = {High, Medium, Low})? For ordered (or binary) factor variants a multilinear model is probably more appropriate.



Thank for your answer. Yes the factors are dicrete (Mean 1, 2..) method (1,2,3..) Sometimes I have 5 or 6 factors. if the factors have 2 or 3 terms, it is still possible to use a quadratic linear model, but it is more difficult when the number of terms
exceeds 3.
Meta numerics is a very usefull tool... thank
Maurice
