CIest | R Documentation |

Get point estimate and its confidence interval with given contrast and alpha value using t distribution.

CIest(Formula, Data, Term, Contrast, conf.level=0.95)

`Formula` |
a conventional formula for a linear model |

`Data` |
a |

`Term` |
a factor name to be estimated |

`Contrast` |
a level vector. Level is alphabetically ordered by default. |

`conf.level` |
confidence level of confidence interval |

Get point estimate and its confidence interval with given contrast and alpha value using t distribution.

`Estimate` |
point estimate of the input linear constrast |

`Lower CL` |
lower confidence limit |

`Upper CL` |
upper confidence limit |

`Std. Error` |
standard error of the point estimate |

`t value` |
value for t distribution |

`Df` |
degree of freedom |

`Pr(>|t|)` |
probability of larger than absolute t value from t distribution with residual's degree of freedom |
