cvtype.image: Generating test dataset index of two-dimensional data for cross-validation

Description

This function generates test dataset index of two-dimensional data for cross-validation

Usage

cvtype.image(n, cv.bsize=c(1,1), cv.kfold)

Arguments

n

the size of image

cv.bsize

two-dimensional block size of cross-validation

cv.kfold

the number of fold of cross-validation

Value

• Two matrix representing test dataset index of each dimension for cross-validation.
• cv.index1
  each row is test dataset index of one dimension
• cv.index2
  each row is test dataset index of the other dimension

Details

This function provides indexes of two-dimensional cross-validation scheme. Only random cross-validation scheme is provided.
