用拉丁超立方和正交抽样法研究模型总体、试验设计和参数空间的覆盖

Populations of models, Experimental Designs and coverage of parameter space by Latin Hypercube and Orthogonal Sampling

Kevin Burrage, Pamela Burrage, Diane Donovan, Bevan Thompson

摘要:

在本文中,我们已经使用模拟作出的覆盖范围的$t$维子空间的$d$维参数空间的大小为$n$进行$k$试验时,拉丁超立方体采样的猜想。其形式为$P(k,n,d,t)=1-e^{-k/n^{t-1}}$。我们认为这个覆盖率公式是独立于$d$的,这使我们能够在构建模型总体和试验设计之间建立联系。我们还表明,正交采样是优于拉丁超立方体采样方面,允许更均匀的覆盖率的$t$维子空间的子块大小的水平。

英文摘要:

In this paper we have used simulations to make a conjecture about the coverage of a $t$ dimensional subspace of a $d$ dimensional parameter space of size $n$ when performing $k$ trials of Latin Hypercube sampling. This takes the form $P(k,n,d,t)=1-e^{-k/n^{t-1}}$. We suggest that this coverage formula is independent of $d$ and this allows us to make connections between building Populations of Models and Experimental Designs. We also show that Orthogonal sampling is superior to Latin Hypercube sampling in terms of allowing a more uniform coverage of the $t$ dimensional subspace at the sub-block size level.
