I have 5 groups of very different sizes. I want to know if various attributes are the same for the groups when I have corrected for the differences in size, e.g.
> Nordjylland_CG #smallest group A B C D E 0 0 96 9 29 > Hovedstaden_CG #largest group A B C D E 0 7 457 93 158
My idea is to sum across the categories and divide by the sum so that I get normalised or scaled numbers in stead of raw counts.
The counts can be assumed to be poisson distributed, but what is the distribution of the scaled counts (I'm using R with glm to do anova analysis of them)?
