Block-diagonal covariance estimation and application to the Shapley effects in sensitivity analysis
Baptiste Broto, François Bachoc, Laura Clouvel +1
In this paper, we aim to estimate block-diagonal covariance matrices for Gaussian data in high dimension and in fixed dimension. We first estimate the block-diagonal structure of t…

Variance reduction for estimation of Shapley effects and adaptation to unknown input distribution
Baptiste Broto, François Bachoc, Marine Depecker
The Shapley effects are global sensitivity indices: they quantify the impact of each input variable on the output variable in a model. In this work, we suggest new estimators of th…
