similar to: Inaccurate qgamma() (PR#11030)

Full_Name: Morten Welinder Version: 1.5.1 OS: Solaris Submission from: (NULL) (65.213.85.136) I was having problems with qgamma's precision in the sense that pgamma(qpgamma(x)) was not as close to the identity function as I would like. I was seeing relative errors with random input of about 1e-8. This fits nicely with the code'd EPS2 value of 5e-7. To solve this I added a newton step

Hello, I have been working with various probability distributions in R, and it seems the gamma distribution is inaccurate for some inputs. For example, qgamma(1e-100, 5e-101, lower.tail=FALSE) gives: 1.0. However, it seems this is incorrect; I think the correct answer should be 0.082372029620717283.

I was hoping that AR''s find_by_* magic methods would help me retrieve multiple items somewhat like the following: names_to_find = [''Larry'', ''Moe'', ''Curly''] found_people = Person.find_by_name(names_to_find) Is there a way to accomplish this using find_by_* (or even find(:all) using some sort of conditions) or must I resort to SQL

Hi, A project came up that has made me realize that it''s time to learn RoR. I''ve got everything up and running (Ruby 1.8.6, Rails 2.1, MySQL 5, Webrick) and am using Aptana with RadRails for development.
