WebThe sample uniformity (often measured via a discrepancy criterion) is achieved using distance-based criteria (ϕ p or Maximin), that is, criteria normally used in space-filling designs. We show that the standard intersite metrics employed in distance-based criteria (Maximin and ϕ p (phi)) do not deliver statistically uniform designs. unf math lab

In , a Latin Hypercube sampling strategy was used to sample a parameter space to study the importance of each parameter of an epidemic model.Such analysis is also called a sensitivity analysis. Since the dimensionality of the problem is high (6), it is computationally expensive to cover the space.

WebLatin Hypercube Sampling, which is an extension of strati ed sampling, aims at ensuring that each of the scalar input has the whole of its range well scanned, according to a probability distribution5(McKay et al., 1979; Fang et al., 2006). Web1 jan. 2010 · In a hypercube the standard strategy consists of taking a maximin design within a class of Latin hypercube designs. However, in a non hypercubic context, it does not make sense to use the Latin hypercube sampling. A theoretical justification to maximin and minimax criteria with regard to the kernel interpolation is first provided.
