Dear Listers,

I measured pollen grains (variable POLLEN_SIZE) of anthers from three
levels from the same species (variable ANTHER) in many populations
(variable POP). I am most interested in pollen size overlapping among the
three levels among populations. The number of measures per level and per
population varies from 2 - 60 individuals, due the number of flowers
available in each population.

I tried to use some Mixed Models to analyze my data, but it seems to be
over parameterized, besides unbalanced (and I don’t know how to handle with
it!). I believe that reducing the pollen size per population in a global
overlapping index could be a good way to use it as response variable in
models.

I have searched for overlapping index, but I could not find any global
index for my case. I have only found some pairwise overlapping index.

So, my questions are, 1) Is it possible to use some global overlapping
index to quantify how much overlapped are the anther levels in each
population? 2) Does anyone know if there is any function developed to r to
my case?

Any suggestions are welcome.

Best wishes

Nicolay
