Hello! I urgently need to know if it is possible (and if so, how to do) to get the "Estimatet marginal means" from an ANOVA. Or explained more coplicated: It's about plants sewn in 2 densities & 2 patterns. The Variable is biomass and I also use a Covariate. There are highly significant differences between density & pattern but I don't know which of the 2 densities gives the higher biomass values. I would like to get something analoge to the "Estimatet Marginal Means" you get with SPSS. Who can help me as soon as possible? Thanks Deborah Renz ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/
Heeeeeelp! Estimatet Marginal Means of ANOVA needed!

Have you considered feeding the ANOVA fit to "predict"? A second alternative might be "tapply". hope this helps. spencer graves
