In this paper we present a novel analysis of a random sampling approach for three clustering problems in metric spaces: k-median, min-sum k-clustering, and balanced k-median. For all these problems we consider the following simple sampling scheme: select a small sample set of points uniformly at random from V and then run some approximation algorithm on this sample set to compute an approximati...

Pseudo-random numbers – both uniform and non-uniform – are used in random sampling, simulation, and Monte-Carlo estimation. Base SAS software contains numerous random number, quantile, and probability functions allowing the user to generate a selection of nominal, discrete, and continuous random variates. Other variates may be generated with a data step, often making use of SAS functions. We wi...

BACKGROUND Cluster sample surveys of health and nutrition in rural areas of developing countries frequently utilize the EPI (Expanded Programme on Immunization) method of selecting households where complete enumeration and systematic or simple random sampling (SRS) is considered impractical. The first household is selected by choosing a random direction from the centre of the community, countin...

In situations where the experimental or sampling units in a study can be easily ranked than quantified, McIntyre (1952, Aust. J. Agric. Res., 3, 385-390) proposed that the mean of n units based on a ranked set sample (RSS) be used to estimate the population mean, and observed that it provides an unbiased estimator with a smaller variance compared to a simple random sample (SRS) of the same size...
