Draw Random Subsamples
Set up weight matrix for subsampling with sample proportion 1/2
to be used with stabsel.
subsample(weights, B = 100, strata = NULL)
weights |
a numeric vector of weights for the model to be cross-validated. |
B |
number of folds, per default 25 for |
strata |
a factor of the same length as |
The function subsample can be used to build an appropriate
weight matrix to be used with stabsel. See there for
more details.
If strata is defined sampling is performed in each stratum
separately thus preserving the distribution of the strata
variable in each fold.
## just a low-dimensional example subsample(weights = rep(1, 10), B = 50)
