Overview

About

Maintained by Jouni HelskeFirst published 2016-11-305 releasesCRAN page ↗GitHub ↗

Function for adapting the shape of the random walk Metropolis proposal as specified by robust adaptive Metropolis algorithm by Vihola (2012) doi:10.1007/s11222-011-9269-5. The package also includes fast functions for rank-one Cholesky update and downdate. These functions can be used directly from R or the corresponding C++ header files can be easily linked to other R packages.
