I am new to stats and R and am unsure what test to use to analyze my data.
I am wanting to find out if the number of individuals in each category is significantly different. There are 11 categories A-K. It is not independent as sightings could be the same individuals over time.
I was suggested to do a mixed-model test so have tried to do an anova using lmer followed by pairwise Bonferroni,
which works but I don't think is right with the columns I have (what to use as the random variable ( +(1|.?.))and while it works the pairwise results are also not what I would expect.
Any help or direction would be much appreciated
