%description
The active subspace method is a sensitivity analysis technique that finds
important linear combinations of input variables for a simulator. This
package provides functions allowing estimation of the active subspace
without gradient information using Gaussian processes as well as
sequential experimental design tools to minimize the amount of data
required to do so. Implements Wycoff et al. (JCGS, 2021)
<doi:10.48550/arXiv.1907.11572>.
