Once the derivatives are available, the only +additional computational effort is in solving a linear regression problem. +This method has been extended to higher dimensions using regularisation. This +package can be used to easily perform ZV-CV or regularised ZV-CV when a set of +samples, derivatives and function evaluations are available. Additional +functions for applying ZV-CV to two estimators for the normalising constant of +the posterior distribution in Bayesian statistics are also supplied.") + (license license:gpl2+))) |
