Aiming for a representative sample: Simulating random versus purposive strategies for hospital selection.
BACKGROUND A ubiquitous issue in research is that of selecting a representative sample from the study population. While random sampling strategies are the gold standard, in practice, random sampling of participants is not always feasible nor necessarily the optimal choice. In our case, a selection must be made of 12 hospitals (out of 89 Dutch hospitals in total). With this selection of 12 hospi...
متن کاملSelection of a Representative Sample
Sometimes a larger dataset needs to be reduced to just a few points, and it is desirable that these points be representative of the whole dataset. If the future uses of these points are not fully specified in advance, standard decision-theoretic approaches will not work. We present here methodology for choosing a small representative sample based on a mixture modeling approach.
متن کاملComparing representative selection strategies for dissimilarity representations
— Many of the computational intelligence techniques currently used do not scale well in data type or computational performance, so selecting the right dimensionality reduction technique for the data is essential. By employing a dimensionality reduction technique called representative dissimilarity to create an embedded space, large spaces of complex patterns can be simplified to a fixed-dimensi...
متن کاملA fuzzy random multi-objective approach for portfolio selection
In this paper, the portfolio selection problem is considered, where fuzziness and randomness appear simultaneously in optimization process. Since return and dividend play an important role in such problems, a new model is developed in a mixed environment by incorporating fuzzy random variable as multi-objective nonlinear model. Then a novel interactive approach is proposed to determine the pref...
متن کاملA Survey on Simulating Stable Random Variables
In general case, Chambers et al. (1976) introduced the following algorithm for simulating any stable random variables $ X/sim(alpha, beta, gamma, delta) $ with four parameters. They use a nonlinear transformation of two independent uniform random variables for simulating an stable random variable... (to continue, click here)
