View source: R/FrechetVaRPlot2DCl.R

Plots the VaR of a portfolio against confidence level assuming extreme losses are Frechet distributed, for specified range of confidence level and a given holding period.

1 | ```
FrechetVaRPlot2DCl(mu, sigma, tail.index, n, cl, hp)
``` |

`mu` |
Location parameter for daily L/P |

`sigma` |
Scale parameter for daily L/P |

`tail.index` |
Tail index |

`n` |
Block size from which maxima are drawn |

`cl` |
Confidence level and should be a vector |

`hp` |
Holding period and should be a scalar |

Note that the long-right-hand tail is fitted to losses, not profits.
