How to compute the confidence interval of the ratio of two normal means It's very good references, I also like that you actually made a calculator for it (+1). As expected though, in your calculator you clearly state that when the confidence interval of the denominator includes zero, it is not possible to compute the CI of the quotient. I think it's the same that happens when I try solving the quadratic equation. suppose variance is 1, mu1 = 0 and mu2=1, N=10000. It's unsolvable. |

How to sample from a normal distribution with known mean and variance using a conventional programming language? @Arun it is the easiest way. You can also generate from the pdf directly using for example the "acceptance rejection" method. I posted for you a simple example on my site (because not enough space in the comment box here). |

How to sample from a normal distribution with known mean and variance using a conventional programming language? When I posted my answer above I didn't notice that @vitalStatistix gave you the Box-Muller Transform algorithm. The one I give above is also as good I suppose. |

Distribution of a ratio of two proportions It may help you to think of it as a random vector R = (r1, r2) with mean mu = (p1, p2). But I'll doubt anyone could come up with a better answer than Greg Snow gave below. |

Distribution of a ratio of two proportions OK, the closest statistic I could find is called the Location Quotient. However they don't describe a pdf. |

Distribution of a ratio of two proportions Ok thanks but I really would like to know the distribution p1/p2; it would be in similar spirit to what they use as a distribution for the odds ratio or the risk ratio or the (log odds) to be able to estimate statistics of interest like its mean and variance, confidence intervals etc... |
