Stratification in Business and Agriculture Surveys with R [PDF]

open access: yesRevista Română de Statistică, 2016
Usually sample surveys on enterprises and farms adopt a one stage stratified sampling design. In practice the sampling frame is divided in non-overlapping strata and simple random sampling is carried out independently in each stratum.
