    am i approximately chi-squared?

    Is that a threat?

    Standard deviation of an average of a number of results

    I mean... They have the data. They can just compute the percentiles directly. No need for the standard deviation if that's the goal here.

    Well you're not normal that's for sure

    Help writing hypotheses!

    And how do you think the formula for correlation is related to the earlier discussion? Please answer this question.

    What do you see is the relationship between what you quoted and the image you posted?

    Help writing hypotheses!

    @AngleWyrm There may have been an ad hominem but the concerns are real. And if we're being honest there are times where I feel like you're only contributing negatively to the discussion (because what you're contributing is sometimes objectively wrong and misleading to the OP). We appreciate...

    Help writing hypotheses!

    I've asked myself that before

    I never really liked the "Accept Ho" terminology. Change that to "Fail to reject Ho" and it's better.

    Make me pretty (Density Plot)

    change theme(axis.text=element_text(size=14)) to theme(axis.text.x = element_text(size=14), axis.text.y = element_blank())

    Exact Poisson CI

    As it should. But simulating from the likelihood isn't really defensible from a frequentist perspective. I'm being pedantic but if that's what you want to do it really makes the most sense to at least acknowledge you're taking a bayesian approach.

    Exact Poisson CI

    Could use the posterior distribution you'd get from a bayesian analysis for that I would think.

    Exact Poisson CI

    Can you provide a link to any source listing that as "exact"?

    Pick until you get all black balls

    Do you know about combinations and permutations?

    Need help on a statistical algorithm.

    It is. But like you said it must be iid and this ends up with a symmetric distribution which i don't think quite fits the needs here. Plus is a convolution really simpler than an if/else?

    Indeed! I even suggested that algorithm in this post: http://www.talkstats.com/threads/need-help-on-a-statistical-algorithm.78447/post-233103
