What is Latin hypercube designs?

A Latin hypercube design is constructed in such a. way that each of the d dimensions is divided into p equal levels (sometimes called bins) and that there is only one point (or sample) at each level. As originally proposed, a random procedure is used to determine the point locations.

What is Latin hypercube sampling used for?

Latin hypercube sampling (LHS) is a statistical method for generating a near-random sample of parameter values from a multidimensional distribution. The sampling method is often used to construct computer experiments or for Monte Carlo integration.

How many samples are in a Latin hypercube?

Latin Hypercube Sampling: how to decide on sample size of dimensions greater than 3? In a Latin Hypercube Sampling, one needs to follow the orthogonal rule i.e., in each row&column there can be only 1 sample.

How to do Latin hypercube sampling?

One-dimensional Latin hypercube sampling involves dividing your cumulative density function (cdf) into n equal partitions; and then choosing a random data point in each partition. As a simple example, let’s say you needed a random sample with 100 data points. First, divide the cdf into 100 equal intervals.

How to create a Latin hypercube with lhsdesign?

X = lhsdesign (n,p,Name,Value) modifies the resulting design using one or more name-value pair arguments. For example, you can obtain a discrete design by specifying ‘Smooth’,’off’. Create a Latin hypercube sample of 10 rows and 4 columns.

Which is the best description of Latin hypercube sampling?

Latin hypercube sampling. Latin hypercube sampling (LHS) is a statistical method for generating a near-random sample of parameter values from a multidimensional distribution. The sampling method is often used to construct computer experiments or for Monte-Carlo integration.

How to create Latin hypercube randomized design in pydoe?

In this section, the following kinds of randomized designs will be described: Latin-hypercube designs can be created using the following simple syntax: samples: an integer that designates the number of sample points to generate for each factor (default: n)

How to iteratively generate a Latin hypercube sample?

X = lhsdesign (…,’criterion’,criterion) iteratively generates Latin hypercube samples to find the best one according to criterion , which can be ‘none’, ‘maximin’ , or ‘correlation’. No iteration. Maximize minimum distance between points. This is the default. Reduce correlation.
