Can agresti-coull binomial confidence intervals be negative? When I tried binom.confint(0, 5, .95) I got a negative LL. Something is wrong. |

Can agresti-coull binomial confidence intervals be negative? I haven't done any computing (not able to, right now) but looking at the formula for LL, how could it be negative? The numerator is all positive things, isn't it? Or am I missing something? |

Which statistical method should I use? The site will object soon to the length of this thread of comments, which isn't really related to the question, anyway. |

Which statistical method should I use? Re your last paragraph, I think this could make an interesting community discussion. I kind of like DV and IV (and, so far, I've not had anyone get confused and think it was an instrumental variable). Perhaps this varies by field? |

What is the meaning of “All models are wrong, but some are useful” Indeed. It was the Borges story that gave me the idea for the analogy. |

multiple regression and multiple comparisons If you want to edit your question, that's fine, but it's probably better to do it in the question itself, so that people see it first. But I am not sue what "How would you look thought at all of them" means. |

multiple regression and multiple comparisons This looks like a duplicate of (this question)[stats.stackexchange.com/questions/3200/… if it isn't please say why not. |

Which variables have too much variation? Is this a school assignment? If so, please add the "self-study" tag. |

Which variables have too much variation? Sounds like you have ONE variable measured 12 times in each of a thousand lakes. A lake is not a variable |

Correlation vs measure of independence We were typing at the same time, with almost the same thoughts. GMTA :-) |
