1 2 3 |

`x` |
an object of class |

`alpha` |
numeric from interval (0,1) indicating the confidence level for which the boundary of the supF test will be computed. |

`pval` |
logical. If set to |

`aveF` |
logical. If set to |

`asymptotic` |
logical. If set to |

`...` |
currently not used. |

an object of class `"ts"`

with the same time properties as
the time series in `x`

## Load dataset "nhtemp" with average yearly temperatures in New Haven
data("nhtemp")
## plot the data
plot(nhtemp)
## test the model null hypothesis that the average temperature remains
## constant over the years for potential break points between 1941
## (corresponds to from = 0.5) and 1962 (corresponds to to = 0.85)
## compute F statistics
fs <- Fstats(nhtemp ~ 1, from = 0.5, to = 0.85)
## plot the p values without boundary
plot(fs, pval = TRUE, alpha = 0.01)
## add the boundary in another colour
lines(boundary(fs, pval = TRUE, alpha = 0.01), col = 2)
