1. ### Immortality & Bayesian Statistics

This is the case sometimes. Priors can also be purely subjective, or just assume a state of ignorance. Quick sum-up: To apply Bayes theorem to the testing of an hypothesis you need three inputs: P(H), the prior probability that the hypothesis (e.g., that reincarnation exists) is true P(D|H)...
2. ### Immortality & Bayesian Statistics

This bit: Has absolutely zero connection with this bit: It's sort of like saying "All swans I have observed thus far have been white, therefore baked beans are made of aliens". Nothing about your argument makes any sense, you haven't developed any meaningful understanding of Bayes...
3. ### Immortality & Bayesian Statistics

I have an objection: I don't appreciate having our time wasted with this Socratic-questioning nonsense. If you have a question to post, just post it (in full).
4. ### Density of hair in left and right armpits and Paired T-Test

Thanks, but I should learn to read the replies before posting to the OP, because you'd already nicely covered most of what I was going to say :)
5. ### Density of hair in left and right armpits and Paired T-Test

I think your choice of a paired t-test makes sense, but do keep in mind here that a non-significant result will not "prove" the null to be true. In general, we cannot use statistical analyses to "prove" things; "proof" implies absolute certainty, and statistical analyses always come with some...
6. ### Which statistical test to use

I haven't looked at your data so I might be missing something here, but it isn't immediately clear to me how you would be able to use statistics to answer your research question. The question of whether a particular asset is a "good" investment is not really a statistical question: One would...
7. ### Alpha 0.1 and power 75% is it acceptable

I don't see how the population-sample distinction is relevant here? No one is saying p values are sacred. You don't have to think they're sacred to be against p hacking. Yes, you can just report effect sizes and p values and leave it to others to decide what they mean. But then the OP wouldn't...
8. ### Alpha 0.1 and power 75% is it acceptable

There is a move away from statistical significance testing, and setting alpha at 0.05 is indeed somewhat arbitrary. Some of usthink it can be fine to commit to an alpha level other than 0.05, depending on the circumstances of a particular study... But you still have to set the alpha level in...
9. ### Alpha 0.1 and power 75% is it acceptable

Is this the case, OP? I hope you haven't decided to switch to a higher alpha level after observing a non-significant result?
10. ### Bootstrap bca confidence intervals for large number of statistics (boot)

(This isn't really a question thread - I'm just providing some possibly useful code, and asking for suggestions on how it can be improved). The boot.ci function in the boot package allows users to get confidence intervals for particular statistics, with the limits obtained via bootstrapping...
