I have a dataset (positive count data) with bimodal shape. My theory is that the sample is composed of samples drawn from two different populations. I have another large dataset that I assume is a sample of one of the subpopulation. The data again is counts of occurrences (all positive and positively skewed, I wouldn't want to assume any distributions at this time). My question is: can I derive some information about the other subpopulation like mean and variance without further assumptions on distributions of the populations or weights of how the bimodal sample drawn from the two populations?
