Given a penalized.pls. object, and new data, this function predicts the response for all components.

1 | ```
new.penalized.pls(ppls, Xtest, ytest = NULL)
``` |

`ppls` |
Object returned from penalized.pls |

`Xtest` |
matrix of new input data |

`ytest` |
vector of new response data, optional |

`penalized.pls`

returns the intercepts and regression
coefficients for all penalized PLS components up to `ncomp`

as
specified in the function `penalized.pls`

. `new.penalized.pls`

then computes the estimated response
based on these regression vectors. If `ytest`

is given, the mean squared
error for all components are computed as well.

`ypred` |
matrix of responses |

`mse` |
vector of mean squared errors, if ytest is provided. |
