Tīmeklis2024. gada 11. sept. · Sampling is a method that allows us to get information about the population based on the statistics from a subset of the population (sample), without having to investigate every individual. The above diagram perfectly illustrates what sampling is. Let’s understand this at a more intuitive level through an example. Tīmeklis(3) the method of Rao, Hartley and Cochran (1962) and (4) Lahiri's (1951) method using a ratio estimator. The methods of Brewer, Durbin and Rao (1965) are equivalent in that they have the same joint probabilities of selection and, hence, the same variance. However, Durbin's method has the advantage of allowing for rotation of the sample.
