Hi all I am hoping to use the SamplingStrata R package for a dataset describing a population of businesses wherein I have information on the type of business, as well as, for designated employment number bands, number of employees and business turnover information. So ideally the stratification will be business type X business size. I am not 100% sure what "domains" (in the vernacular of the package) would be referring to in this case? Also can I employ both number of employees and business turnover information to optimise the stratification sampling procedure? thank you in advance [[alternative HTML version deleted]]
