Description Usage Arguments Details Value See Also Examples
The function randomly generates fold data for cross-validation
1 | do.stratified.cv.data(examples, positives, k = 10, seed = 0)
|
examples |
vector of integer: indices of the examples |
positives |
vector of integer: Indices of the positive examples. The indices refer to the indices of |
k |
number of folds (def = 10) |
seed |
seed of the random generator (def=0). If is set to 0 no initialization is performed |
he folds are separated for positive and negative examples. The elements included in each fold are obtained by random sampling the data.
a list with two components;
fold.non.positives |
a list with |
old.positives |
a list with |
do.stratified.cv.data.from.folds
1 | do.stratified.cv.data(1:100, 1:20, k = 10)
