[R] pls package

Hi All, I am using the cppls function in the pls package, and I want to use cross validation to determine the best number of components. Since Hastie et al recommended a "one standard error rule", i.e., choose the most parsimonious model whose error is no more than one standard error above the err

[R] integration

Hi, All, I have a density function with 3 variables which is defined on some irregular domain, and I want to get the marginal distribution of each variable. Is there any function doing this? A simple example is p(x,y,z)=x*y*z*I(xy>z). So each marginal distribution is a function of the other two v

Re: [R] pairs

Do you mean if the numbers in each row are ordered? They are not, but if it's needed, we can order them. The matrix only has 5000 rows. On Mon, Nov 16, 2009 at 1:34 PM, David Winsemius wrote: > > On Nov 16, 2009, at 2:32 PM, cindy Guo wrote: > > I forgot to say that there ar
