Comparing multiple distributions
...cture etc.). So my data is special in that, at each
sampling site (each observation), I don't have *one* number, I have
*several* numbers (abundance of organisms in each depth bin, I sample
5 depth bins) which describe a vertical distribution.
Then let say I want to compare speciesA with speciesB, I would end up
trying to compare a group of several distributions with another group
of several distributions (where a "distribution" is a vector of 5
numbers: an abundance for each depth bin). Does anyone know how I
could do this (with R obviously ;) )?
Currently I kind of get...

mixed-effects model with two fixed effects: interaction
Dear all,
In a greenhouse experiment we tested performance of 4 different species (B,H,P,R) under 3 different water levels in 10 replications. As response variable e.g. the number of emerging sprouts were measured on three dates. A simple Anova considering every measurement date separately shows a higly significant effect of species and moisture (and partly the interaction of both). The
