[R] Using boot.ci to find lower confident bound
Dear R-users, I am trying to find lower confident bound (one side CI) for a variable of interest using boot.ci command in bootstrap method. In the boot.ci, it provides 5 methods for finding CI (two-side CI). Anyone can help me with that? Or any suggestions? Do I have to use a different commands?

Re: [R] Using boot.ci to find lower confident bound
Start by reading the references in ?boot.ci, to understand the different methods. Then you pays your money and you takes your choice. (Hint: R is free.) Cheers, Simon.

Re: [R] Using boot.ci to find lower confident bound
I think the question was 'how do I get one-sided confidence limits from package boot?' As far as I know you would have to rewrite the code to do so, and this looks pretty simple. Simon is right to point out that you need to understand the methods: some of these methods are much worse for one-sided limits, especially the so-called 'basic' method.
