Overview . Latin Hypercube Sampling (LHS) is a method of sampling a model input space, usually for obtaining data for training metamodels or for uncertainty analysis.LHS typically requires less samples and converges faster than Monte Carlo Simple Random Sampling (MCSRS) methods when used in uncertainty analysis. Latin hypercube sampling is similar to these topics: Sampling distribution, Metropolis–Hastings algorithm, Convolution random number generator and more. 5 Oct 2020 ples and Orthogonal Array Latin Hypercube Samples.

Sampling methods as Latin hypercube, Sobol, Halton and Hammersly take advantage of the fact that we know beforehand how many random points we want to sample. Then these points can be “spread out” in such a way that each dimension is explored. See also the example on an integer space sphx_glr_auto_examples_initial_sampling_method_integer.py Latin Hypercube Sampling (LHS)¶ LHS is a stratified random sampling method originally developed for efficient uncertainty assessment. LHS partitions the parameter space into bins of equal probability with the goal of attaining a more even distribution of sample points in the parameter space that would be possible with pure random sampling.

In this ED method, the input space is partitioned in different “strata,” and a representative value is selected from each stratum.
