sparseHessianFD (version 0.3.3.7)

Numerical Estimation of Sparse Hessians

Description

Estimates Hessian of a scalar-valued function, and returns it in a sparse Matrix format. The sparsity pattern must be known in advance. The algorithm is especially efficient for hierarchical models with a large number of heterogeneous units. See Braun, M. (2017) .
