subsample {stabs} | R Documentation |
Draw Random Subsamples
Description
Set up weight matrix for subsampling with sample proportion 1/2
to be used with stabsel
.
Usage
subsample(weights, B = 100, strata = NULL)
Arguments
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 |
Details
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.
