Dataset Name: DanWood (DanWood.dat) | |

File Format: ASCII | |

Starting Values (lines 41 to 42) | |

Certified Values (lines 41 to 47) | |

Data (lines 61 to 66) | |

Procedure: Nonlinear Least Squares Regression | |

Description: These data and model are described in Daniel and Wood | |

(1980), and originally published in E.S.Keeping, | |

"Introduction to Statistical Inference," Van Nostrand | |

Company, Princeton, NJ, 1962, p. 354. The response | |

variable is energy radieted from a carbon filament | |

lamp per cm**2 per second, and the predictor variable | |

is the absolute temperature of the filament in 1000 | |

degrees Kelvin. | |
