Specifies the output to be displayed.

Model |
Displays the model. |

Summary |
Summary of the analysis. |

Estimates |
Displays estimates of the parameters and confidence interval for the x location of the intersection (or breakpoint) of the lines. |

Fitted values |
Displays the fitted values. |

Intercepts |
Displays the x-value at which the model intercepts the y-axis, and the y-value at which it intercepts the x-axis. |

## Confidence limit (%)

Specifies the confidence limit for the x location of the intersection (or breakpoint) of the lines. This value should be supplied as a percentage.

## Number of grid points for initial search

Specifies the number of grid points used in the initial search for the best point.

## Graphics

Specifies the plots to be displayed.

Breakpoint |
