est_options | R Documentation |

Sets starting values, upper and lower bounds for the parameters. The bounds are based on those in the rvinecopulib package.

```
est_options(family, tau = 0.5)
```

`family` |
Copula family: "gaussian", "t", "clayton", "frank", "gumbel", "joe", "plackettâ€ť, "bb1", "bb6", "bb7","bb8","ncs-gaussian", "ncs-clayton", "ncs-gumbel", "ncs-frank", "ncs-joe","ncs-plackett". |

`tau` |
Estimated Kendall's tau to compute a starting point (default is 0.5) |

`LB` |
Lower bound for the parameters |

`UB` |
Upper bound for the parameters |

`start` |
Starting point for the estimation |
