WebbNote that this sampling is probability proportional to size with replacement (PPSWR). We don’t remove a farm (or a cow) from the list once it has been selected. This is necessary since there is no (known? possible?) way to select a probability proportional to size (PPS) sample without replacement. WebbBecause selection probabilities cannot exceed 1, the relative size for each unit must not exceed for METHOD=PPS. This requirement can be expressed as , or equivalently, . If your size measures do not meet this requirement, you can adjust the size measures by using the MAXSIZE= or MINSIZE= option. the three tuns staple kent https://brain4more.com
