doe_saltelli — MULTIVAR sensitivity op

• 数据种类:无 → design(仅由参数决定的算子 —— 不接受图像或数据输入)

• 调用: import fullseye as fs; fs.ledger.doe_saltelli(n=1024, factors=3, seed=0) -> 'dict'(要直接调用实现,import sensitivity; sensitivity.doe_saltelli(n=1024, factors=3, seed=0) -> 'dict';从台账取用则 opsmultivar.get("doe_saltelli"))

用法

用于 Sobol' 指数的样本矩阵(Saltelli 等 2010)-> 共 n (k + 2) 次运行的 design。

> 以下的详细说明为原文 —— 摘要与标题已翻译。

A Sobol' sequence of dimension 2k gives two independent n x k matrices A (first k columns) and B (last k). For each factor i, A_B^(i) is A with column i taken from B. Rows are stacked as [A; B; A_B^(1); ...; A_B^(k)] (meta['blocks']), which is the layout sens_sobol reads.

n must be a power of two: the balance properties of a Sobol' sequence hold for 2^m points, and the estimators' error behaves erratically otherwise — the op refuses rather than silently degrading. seed scrambles the sequence (Owen scrambling via scipy); seed=None uses the plain sequence.
