# Draw Random Subsamples

### Description

Set up weight matrix for subsampling with sample proportion *1/2*
to be used with `stabsel`

.

### Usage

1 |

### 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.
