1. ### am i approximately chi-squared?

Is that a threat?
2. ### 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.
3. ### am i approximately chi-squared?

Well you're not normal that's for sure
4. ### Help writing hypotheses!

And how do you think the formula for correlation is related to the earlier discussion? Please answer this question.
5. ### Help writing hypotheses!

What do you see is the relationship between what you quoted and the image you posted?
6. ### 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...

8. ### Help writing hypotheses!

I never really liked the "Accept Ho" terminology. Change that to "Fail to reject Ho" and it's better.
9. ### 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())
10. ### 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.
11. ### Exact Poisson CI

Could use the posterior distribution you'd get from a bayesian analysis for that I would think.
12. ### Exact Poisson CI

Can you provide a link to any source listing that as "exact"?
13. ### Pick until you get all black balls

Do you know about combinations and permutations?
14. ### 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?
15. ### Need help on a statistical algorithm.

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

Honestly that's probably a better suggestion for this. Going the full Beta route might be nicer if it's possible to code easily but the triangle distribution would probably work quite well here. I guess it all comes down to the specifics of what attributes are necessary from the distribution.
17. ### Need help on a statistical algorithm.

@AngleWyrm were you perhaps trying to illustrate inverse transform sampling but got the details wrong? https://en.m.wikipedia.org/wiki/Inverse_transform_sampling
18. ### Need help on a statistical algorithm.

@Bman28 let me know if my suggestions on how to do it in Lua help or not. I'm not sure if any of that requires any external packages or whatever because I don't use Lua but wanted to help.
19. ### Need help on a statistical algorithm.

@AngleWyrm .... Are you trying to help? There might be a crumb of usefulness in that post but almost every contribution to this thread that you've made is a net detriment in my mind. You post some things that are kind of related but aren't really useful to what they're trying to do. Maybe...
20. ### Need help on a statistical algorithm.

Actually I might not have read closely enough. I think you can directly sample - you just need to provide a prng instead of a qrng. If that's the case it should be as easy as creating the distribution object and calling it's sample method with a prng of your choosing.
