Sliced Latin hypercube designs via orthogonal arrays
Computer experiments are becoming increasingly popular in studying complex real world systems. A special class of sliced Latin hypercube design is proposed in this paper. Such designs are particularly suitable for computer experiments with both qualitative and quantitative factors, multi-fidelity computer experiments, cross-validation and data pooling. The resulting sliced Latin hypercube desig...
متن کاملConstruction of Orthogonal and Nearly Orthogonal Latin Hypercube Designs from Orthogonal Designs
Latin hypercube designs (LHDs), widely used for computer experiments, are a very large class of designs with desirable properties. Recently, a number of methods have been proposed to construct orthogonal LHDs. In this paper, we introduce an approach to constructing 2-order orthogonal designs. The methods are simple and easy to implement. Using orthogonal designs, we propose some methods for con...

متن کاملConstruction of Nested Orthogonal Latin Hypercube Designs
Nested Latin hypercube designs (LHDs) are proposed for conducting multiple computer experiments with different levels of accuracy. Orthogonality is shown to be an important feature. Little is known about the construction of nested orthogonal LHDs. We present methods to construct them with two or more layers, making use of orthogonal designs. The constructed designs possess the property that the...
متن کاملThe Lasso with Nearly Orthogonal Latin Hypercube Designs
We consider the Lasso problem when the input values need to take multiple levels. In this situation, we propose to use nearly orthogonal Latin hypercube designs, originally motivated by computer experiments, to significantly enhance the variable selection accuracy of the Lasso. The use of such designs ensures small column-wise correlations in variable selection and gives flexibility in identify...
