ith_mbl_neighbor: An iterator for local prediction data in mbl

Description Usage Arguments Details Value Author(s)

View source: R/local_helpers.R

Description

internal function. It collects only the data necessary to execute a local prediction for the mbl function based on a list of neighbors. Not valid for local dissmilitary (e.g. for ortho_diss(...., .local = TRUE))

)

Arguments

Xr

the Xr matrix in mbl.

Xu

the Xu matrix in mbl.

Yr

the Yr matrix in mbl.

Yu

the Yu matrix in mbl.

diss_usage

a character string indicating if the dissimilarity data will be used as predictors ("predictors") or not ("none").

neighbor_indices

a matrix with the indices of neighbors of every Xu found in Xr.

neighbor_diss

a matrix with the dissimilarity socres for the neighbors of every Xu found in Xr. This matrix is organized in the same way as neighbor_indices.

diss_xr_xr

a dissimilarity matrix between sampes in Xr.

group

a factor representing the group labes of Xr.

Details

isubset will look at the order of knn in each col of D and re-organize the rows of x accordingly

Value

an object of class iterator giving the following list: itemize
