SwPA-PLS provides the influence of each variable without considering the influence of the rest of the variables through sub-sampling of samples and variables.

1 2 | ```
spa_pls(y, X, ncomp = 10, N = 3, ratio = 0.8, Qv = 10,
SPA.threshold = 0.05)
``` |

`y` |
vector of response values ( |

`X` |
numeric predictor |

`ncomp` |
integer number of components (default = 10). |

`N` |
number of Monte Carlo simulations (default = 3). |

`ratio` |
the proportion of the samples to use for calibration (default = 0.8). |

`Qv` |
integer number of variables to be sampled in each iteration (default = 10). |

`SPA.threshold` |
thresholding to remove non-important variables (default = 0.05). |

Returns a vector of variable numbers corresponding to the model having lowest prediction error.
