.hessian | R Documentation |

We perform a quick check about the expected runtime and adjust the precision accordingly.

.hessian(f, x, seconds.warning = 60, default.r = 6, min.r = 2, ...)

`f` |
function to compute Hessian for |

`x` |
location to evaluate Hessian at |

`seconds.warning` |
time threshold in seconds to trigger message and reduce the number of iterations for Richardson extrapolation of numDeriv::hessian |

`default.r` |
default number of iterations (high-precision recommendation of numDeriv) |

`min.r` |
minial number of iteration, must be at least 2, |

`...` |
further arguments passed to method.args of numDeriv::hessian |
