Jan 20, 2017 at 22:58 | comment | added | Paul B. Slater | Thanks, Glen-b. Well, I was speculating that the residuals might have some underlying structure--that since they are all nonnegative on [0,1]--might, at least, be proportional to one of the known probability distributions on that interval. In any case, this is all quite exploratory/tentative in nature. | |
Jan 20, 2017 at 3:37 | comment | added | Glen_b | Aren't you actually trying to fit your data rather than approximate the distribution that approximates the data (these residuals you mention)? (And if so, why are you trying to do that? What is the use to which you'll put the fitted distribution?) | |

added paragraph--in response to the comment of whuber

Jan 19, 2017 at 19:18 | comment | added | whuber♦ | I cannot match that distribution to your function unless I (a) change $\alpha$ to approximately $2.3$ and (b) divide it by approximately $47$. You seem only to be attempting to approximate a function of $\varepsilon$ by a formula of the form $C\varepsilon^{\alpha-1}(1-\varepsilon)^{\beta-1}$--but what does that have to do with "distributions," "mechanisms," or anything else statistical? It appears that for us to be able to address your question you would (at a minimum) have to explain what your point collection means. | |
