Local linear regression
...performs a local linear regression (to give conditional expectation which I
am interested in and not graph) in order to double-check the results?
By the way the code that I wrote is the following (based on the equation
2.50 of Li & Racine book's page 81):
#x should be a 1xq matrix, X is a Nxq matrix of the q regressors, Y is the
response variable Nx1 matrix,
#bw should the 1xq matrix of bandwidths
LL.reg <- function(Y, X, x, bw){
N <- nrow(Y)
q <- ncol(X)
dX <- X-matrix(x, N, q, T)
kx <- dnorm(dX/matrix(bw, N, q, T))
K <- as.vector(apply(kx, 1, function(z) prod(z...

CRAN (and crantastic) updates this week
...terface to Fortran implementations by M. J. D. Powell
* mixOmics (2.6)
Kim-Anh Le Cao
http://crantastic.org/packages/mixOmics
The package supplies two efficients methodologies: regularized CCA and
sparse PLS to unravel relationships between two heterogeneous data
sets of size (nxp) and (nxq) where the p and q variables are
measured on the same samples or individuals n. These data may come
from high throughput technologies, such as omics data (e.g.
transcriptomics, metabolomics or proteomics data) that require an
integrative or joint analysis. However, mixOmics can also be appl...
